Understanding the roles of the server

Network or community infrastructure is the grouping of units and software elements needed to connect units inside a corporation and to merge the group with different organizations and the Web. The bodily infrastructure and logical elements of the network infrastructure are wanted to offer community options, together with connections, routing and switching capabilities, community safety, and entry control. A community or community infrastructure must exist before a number of servers are required to help purposes that customers want in a community surroundings.

Subsequently, when planning a community and deciding on the computers on your network, you have to know your pc's efficiency. Understanding these features provides the community designer a very good place to determine the hardware and software elements needed by computer systems.

Windows Server 2003 itself presents a number of options and tools when installed on a computer. Further options and performance are required on the server to offer the providers and features that a corporation and its users need. In reality, until these further options and features make sure providers out there, the pc cannot be used as a consumer.

Networking computer systems might be grouped in accordance with the following roles:

  • Server roles – servers could be configured to carry out multiple roles. The purposes used by the server outline the position of a specific server. Servers often need providers and additional options which are put in to perform its particular position. In comparison with workstations, servers have more disk area and extra reminiscence and quicker processors. The position of the server determines which units the servers need. Listed here are some widespread server roles:
    • Area Server
    • Database Server

  • Desktop Workstations – Desktops Totally different From Servers As a result of Desktops are general-purpose computer systems that may perform multiple features.
  • Moveable Workstation Roles – Moveable Workstations are the answer to deliver desktop features
  • Windows Server 2003 launched the idea of server roles. The service roles principally group the associated administrative tasks and provide a selected function or perform for network design. If the server is configured for a selected server position, several different providers, features, and tools are put in on the Windows Server 2003 server. In this approach, the server is about to offer customers with the crucial providers.

    Windows Server 2003 supplies a new software for defining and managing server roles, specifically, managing the Server Management utility. The precise wizard to make use of server roles for computer systems is the Server Configuration Wizard. Configuring the Server Configuration function is included in the server administration program and can also be managed by this utility.

    There are 11 totally different server roles in Home windows Server 2003 that can be configured by specifying the server configuration perform:

    • File server
    • Print server
    • Software server
    • Mail server

    • Distant access server / VPN server [19659007] Community Controllers
    • DNS Server
    • WINS Server
    • WINS Server
    • DHCP Server
    • Streaming Media Server

    File Server Position

    The position of the file server is a extensively used position, when configuring servers on Windows Server 2003 networks. This is because of the position of the file server that stores knowledge for network customers and offers entry to information saved in the file server. The position of the file server is just not obtainable in Windows Server 2003 Net Edition.

    File Servers provide the following performance:

    • Permits users to save lots of information to a central location.
    • The consumer can share information with another consumer

    Some of the options and features of the file server position are:

    • File and folder assets might be shared amongst community customers.
    • Directors can handle the following file server features:
      • Utilizing Information and Folders
      • Disk Area
      • Disk quotas could be carried out to regulate the area customers can use
      • .

    • For file servers with NTFS volumes:
      • NTFS protection can be used to guard information from users who shouldn’t have entry to information and folders.
      • File Encryption (EFS) allows customers to encrypt information, folders, and full disks on NTFS platforms. EFS secures confidential enterprise info from unauthorized entry.
      • The distributed file system (DFS) offers one hierarchical file system that helps to share folders on multiple computers on the community. DFS supplies one logical file system construction by overlaying the underlying file-sharing construction in the digital folder construction. Users only see one file structure, although there are multiple folders on the totally different file servers in the organization.
    • The Offline Information function could be enabled if needed. Offline information permit the consumer to mirror the server information on the native laptop and be sure that the moveable information and server information are synchronized. Offline information make sure that laptop computer users can access server-based information when they don’t seem to be related to the community.

    Understanding the position of the print server

    The position of the print server supplies community printing capabilities. The position of the print server permits the server to be configured to handle community printing features. Users often hook up with a community printer by way of a connection to a print server. A print server is a computer on which printer drivers are situated, which control printers between printers and shopper computer systems. Print servers ship the needed printer drivers to clients via Windows NT, Windows 2000, Windows XP, and Home windows Server 2003. Print servers additionally control communication between printers and shopper computers. Print servers control print queues and also can provide audit logs for jobs printed to customers. A community interface printer is a printer that connects to the network by way of a community card. The position of the print server just isn’t out there in Windows Server 2003 Net Edition

    If you find yourself completed with a print server, make it possible for the print server has enough disk area to store the print jobs waiting for the print queue. It is suggested that a separate, fast drive be used on the print switch system. Customers should think about establishing a print server cluster if their company needs exceptional reliability and performance for printing.

    A number of print server features are:

    • Home windows Management Instrumentation (WMI) Manager Interface (API)
    • Directors can control when print units can be used.
    • Administrators can management access to printers
    • .
    • Print jobs might be paused, resumed, and deleted and seen
    • Printers may be revealed utilizing Lively Listing in order that access to printers might be controlled by Lively Listing accounts.

    Net servers

    The position of the software server makes net purposes and shared purposes accessible to users. The online server sometimes features a copy of the World Broad Site and may also use web-based purposes. Once a Net server is put in, customers can entry Net-based purposes and download information.

    When a Net server is added by way of the position of the software server, the following elements are put in:

    • Internet Info Providers
    • Software Server Console
    • Distributed Transaction Coordinator (DTC)
    • COM +, Element Object Model (COM) Extension

    Internet Info Providers 6.0 (IIS is an integrated Microsoft net server that permits customers to create and handle websites within a corporation. IIS allows customers to create and handle web sites and share and share info over the Internet or intranet. With the launch of Home windows Server 2003, Web Info Providers (IIS) came into being. 6. IIS 6 is included with the 32-bit version of Windows Server 2003 and 64-bit variations. IIS 6 consists of help for multiple protocols and administration instruments that permit customers to configure a server as a Net server, file switch protocol (FTP), or Simple Mail Transport Protocol (SMTP) server. The administration tools included in Windows Server 2003 permit users to manage Web info providers on Windows Server 2003 product platforms.

    Before IIS 6 Net Servers can be used inside an organization, the consumer should first install Home windows Server 2003 or upgrade to Windows Server 2003. When Windows Server 2003 is put in, all variations of Windows Server 2003 as Net model may be installed Configuration Wizard. When users log in for the first time after Windows Server 2003 is installed, the Server Management Wizard starts. To arrange the Server Configuration Wizard, click Add / Take away Position Hyperlink and comply with the Server Configuration Wizard to install Software Server (IIS, ASP.NET).

    Protocols Supported by IIS 6.0, Microsoft Integrated Net Server is listed right here:

    • Hypertext Transfer Protocol (HTTP) is a TCP / IP Software Layer protocol used to hook up with web sites and create net content. HTTP handles the publication of static and dynamic Net content material. The HTTP session consists of a connection, an HTTP request, and an HTTP response.
      1. Port 80 is used for HTTP connections. Shopper connects TCP to server with TCP three-channel handshake
      2. As soon as related, shopper sends HTTP GET request to server.
      3. The server sends the requested net page to the shopper.
      4. HTTP Hold-Alives maintains a TCP connection between the shopper and the server whether it is enabled so that the shopper can request further pages.
      5. If HTTP Hold-Alives is disabled, the TCP connection can be terminated after the requested page is loaded.
    • File Switch Protocol (FTP) is a TCP / IP software layer protocol used to copy information to remote techniques and by way of TCP. FTP allows clients to download and obtain information from an FTP server over the Internet. Users can create and handle FTP servers by means of IIS. An FTP server and an FTP shopper are required to make use of the protocol. The FTP session has a connection, a request and a response.
      1. The shopper establishes a TCP connection to the FTP server by way of port 21.
      2. The client is given a port number above 1023
      3. The shopper sends the FTP command to port 21.
      4. If a buyer requires a second reference to the shopper for knowledge transmission. This connection uses port 20.
      5. The second connection remains in TIME_WAIT mode after the knowledge has been transferred to the shopper. TIME_WAIT mode permits you to transfer further info. TIME_WAIT mode ends when the connection time ends.
    • The Network Communication Protocol (NNTP) is a TCP / IP software layer protocol used to ship community messages to NNTP servers and NNTP shoppers over the Internet. NNTP is a shopper / server and server / server protocol. With the NNTP protocol, the NNTP host can play their record of newsgroups and messages by way of their second host by way of news or push. The NNTP shopper can hook up with the NNTP host to download an inventory of newsgroups and skim messages from newsgroups. With NNTP, customers can implement personal news servers to host discussion teams or implement public news servers to offer customer help and assets to Web customers. It can be defined that users have to authenticate to learn and ship gadgets to newsgroups or be given entry to everyone. The NNTP service can be integrated with the Home windows Indexing Service to crawl the content of newsgroups. It’s also absolutely integrated with Windows Server 2003 events and efficiency monitoring.
    • Easy Mail Transfer Protocol (SMTP) is a TCP / IP software layer protocol that routes and transfers e-mail between SMTP hosts on the Web. SMTP allows IIS machines to perform as an SMTP host for sending e-mail over the Web. IIS can be used as an alternative of Sendmail. SMTP also permits IIS machines to guard e mail servers, comparable to Microsoft Change servers, from malicious attacks by operating between these servers and the Sendmail host from a corporation's Web service provider. SMTP can be used to send e mail from one SMTP host to another. SMTP can’t ship e-mail directly to the customer. E-mail shoppers use POP3 or IMAP to obtain e-mail. Windows Server 2003 includes a POP3 service that permits clients to offer mailboxes and deal with incoming e-mail. If you want to use SMTP as an IIS element, you should first install the SMTP service in case you are utilizing Home windows Server 2003 Edition aside from Home windows Server 2003 Net Version. By default, the SMTP service is put in on Home windows Server 2003 Net Version

    Understanding the Position of E-mail Server

    The e-mail server has community providers by providing the features customers have to send and receive e-mail. An e mail server must exist to allow users to e mail one another. When an e-mail server receives an e-mail message to the consumer, it stores the e-mail message to the meant consumer till it is retrieved from the e-mail server.

    The mail server's main features are:

    • Preserve e-mail info
    • Process shopper requests
    • Receiving incoming e-mail from the Internet

    When the e-mail server position server is configured, the following TCP / IP-based protocols are installed: [19659005] Simple Mail Switch Protocol (SMTP) – TCP / IP Software Layer protocol used to route and switch e mail between SMTP hosts on the Web. IIS 6 have to be installed to put in both SMTP and Submit Office Protocol three (POP3). It’s essential to set up the SMTP service as a result of e-mail servers and shoppers use this service to ship e-mail.

  • Submit Workplace Protocol three (POP3) e-mail shoppers use POP3 or IMAP to obtain e mail. Windows Server 2003 features a POP3 service that permits clients to offer mailboxes and deal with incoming e mail. The POP3 service permits clients to retrieve e-mail messages from the mail server
  • Understanding the position of the terminal server

    Terminal providers have the potential to act as an software server that distant customers can hook up with and carry out periods. The Terminal Providers server runs the purposes. The info response is shipped again to the Terminal Providers buyer. Clients can use terminal providers over an area area community or by means of a wide range of connections. Terminal Providers clients embrace MS-DOS-based shoppers, Home windows for Workgroups, (version 3.11), Windows-based terminals, and Macintosh shoppers.

    When a consumer connects to a Home windows Server 2003 server using Distant Desktop, the server shouldn’t be using the workstation assets. The terminal is simply liable for the keyboard, mouse and display. Every consumer has its own terminal service session. Periods are distinctive and do not affect one another. In this approach, a consumer who connects to a Windows Server 2003 server by way of Remote Desktop acts as a terminal for that server

    When a shopper connects to terminal providers, it creates a Terminal Providers session for the shopper. Terminal Providers handles all processing. Clients use irrelevant bandwidth on the spine once they join. Terminal providers are subsequently fashionable with WAN units with restricted bandwidth. It’s also appropriate for cellular customers who need to carry out intensive processor purposes via a dial-up connection. In this case, the local machine should solely handle the console. When you might want to install or replace purposes, a person instance of the software may be put in or upgraded to the Terminal Providers server. Customers have entry to the software with out having to put in or upgrade it on all machines.

    Remote Desktop Protocol (RDP) is a protocol that manages communication between a computer that uses a terminal and a shopper pc that uses a terminal server shopper. The connection could be established with the terminals of the terminal server. The RDC utility can be used for full terminal server use or can be used for distant management. By default, Remote Desktop Connection is put in on Home windows XP and Home windows Server 2003 operating methods. Nevertheless, a distant desktop connection might be installed on earlier Home windows working techniques akin to Home windows 2000, Home windows NT, Windows ME, Windows 98, and Windows 95. The RDC utility is backward suitable and may subsequently work together with terminals in Home windows XP, Home windows 2000, and Home windows NT 4 Terminal Server Edition

  • Understanding the Position of Domain Controller

    Area The controller is a server that shops an Lively Listing writing copy and maintains an Lively Directory repository. Lively Directory is designed to offer a centralized repository that may safely handle organizational assets. Lively Listing listing providers be sure that community assets are available and that users can access these network assets, purposes, and packages. Lively Directory additionally allows administrators to go online to a network pc and manage Lively Listing objects on a special pc in a website.

    A website controller is a computer with Windows 2000 or Home windows Server 2003 that accommodates a replica of the domain listing. Lively Directory area controllers keep an Lively Directory repository and area security coverage. Subsequently, area controllers additionally provide domain safety by authenticating consumer login attempts.

    The primary features of the domain controller position within Lively Directory are:

    • Every domain controller stores and maintains a replica of the Lively Listing repository
    • Lively Listing area controllers use multimaster replication. Which means no single domain controller is the primary domain controller.
    • Domain controllers also routinely replicate directory info for gadgets stored in a website.
    • Essential keepable updates are copied immediately to the the rest of domain controllers. 19659007] Implementing A number of Area Controllers for Your Domain Offers Domain Default Tolerance.
    • Lively Directory domain controllers can detect collisions. Collisions occur when a modified domain attribute in a specific area is changed in a special area controller before the full progress of the unique community controller change.

    Sure grasp roles could be assigned to area and forest domain controllers. Domain controllers assigned particular grasp roles are referred to as Operations Masters. These domain controllers receive a number copy of certain info in Lively Listing. Additionally they copy info to other area controllers. 5 totally different grasp roles could be assigned to area controllers. One area controller is given two varieties of master roles in the forest, forest-based grasp roles. The other three fundamental roles, domain primary roles, apply to the domain controller in each area.

    The primary sort roles that may be configured for domain controllers are:

    • Schema Grasp is a forest
    • Domain Naming Grasp is a forest-wide grasp position that applies to a website controller that manages forest modifications, corresponding to adding and deleting a website. The domain controller that serves this position additionally controls modifications to the domain namespace.
    • Relative Id (RID) is a domain-wide function that applies to a website controller that creates unique ID numbers for area controllers and manages their allocation
    • The PDC emulator is a domain-wide grasp position that applies to a website controller operating as Windows NT: n main domain controller. This position is usually required when computer systems are operating Windows 2000 and XP working techniques.
    • Infrastructure Master is the position of a website that applies to a website controller that manages modifications to group membership [19659016] The International Catalog (GC) server (s) may also be put in in the domain controller. The International Listing is the central repository for Lively Listing Objects for forest and domain, used to enhance performance if you search for Lively Directory gadgets. The first area controller installed in the area is known as by default as a worldwide directory server. The International Listing Server shops a full copy of all host subject objects and partial copies of the the rest of the forest. Partial copy typically accommodates searched gadgets. Usually, it is suggested that you simply configure a worldwide listing server for every area website.

      International listing server features are summarized under. Here, the GC server helps locate the consumer account so that the Genuine Domain Controller can resume the consumer's logon request

    • The International Directory Server handles all search requests for customers looking for info from Lively Listing. It could possibly find all Lively Listing info regardless of the area the place the knowledge is stored. The GC server handles the complete forest request.
    • The worldwide listing server permits customers to offer Universal Group membership info to the area controller for community request requests.

    Understanding the DNS Server Position

    A DNS service is a hierarchically distributed database that creates hierarchical names that can be resolved by IP addresses. The IP addresses are then resolved as MAC addresses. DNS supplies instruments for naming IP hosts and locating IP hosts when prompted by identify.

    The position of the DNS server solves IP addresses as domains and domains as IP addresses. On this means, DNS supplies identify resolution providers to hook up with clients who have to resolve IP addresses. A totally qualified area identify (FQDN) is a DNS identify that is used to determine a pc on a network.

    A DNS server is a computer that has a DNS service or BIND that provides area providers. The DNS server manages the DNS database it incorporates. The DNS database info for the DNS server applies to an element of the tree construction or namespace of the DNS area. This info supplies solutions to buyer requests for accuracy of the identify. The DNS server is authoritative for the adjoining portion of the DNS namespace by which it is situated.

    When a DNS server asks for a reputation for precision providers, it will possibly do one of the following:

    • Answer instantly by request
    • Enter a cursor (reference) to another DNS server that may assist resolve the question.
    • Corresponds that knowledge shouldn’t be obtainable.
    • Answer that there isn’t a knowledge.

    Server roles might be configured for DNS servers. The server position assigned to the DNS server impacts the following features of the server:

    • The best way the DNS server stores DNS info.
    • How DNS Server Maintains Info
    • Is DNS Knowledge

    The totally different DNS server roles that may be specified are:

    • Commonplace Main DNS Server – This DNS server is owned by the DNS database defined zones and should make modifications to its zones. An ordinary main DNS server obtains zone info from an area DNS database. The first DNS server is dependable for the zone knowledge it accommodates. When you might want to make a change to the useful resource resource in the zone, it have to be executed on the main DNS server to be included in the local zone database. The DNS main server is created when a new main zone is added.
    • Regular Secondary DNS Server – This DNS server retrieves read-only copies of zones by means of DNS zone transfers. The secondary DNS server can’t make modifications to the knowledge in the learn copy only. Nevertheless, the secondary DNS server can resolve queries about the identify resolution. Toissijaiset DNS-palvelimet toteutetaan yleensä vian sietokyvyn aikaansaamiseksi, etäyhteyksien asiakkaiden nopean käytön varmistamiseksi ja DNS-palvelimen käsittelykuormituksen jakamiseksi tasaisesti. Jos toissijainen DNS-palvelin on toteutettu, DNS-palvelin voi edelleen käsitellä kyselyitä, kun ensisijainen DNS ei ole käytettävissä. Toissijaiset DNS-palvelimet auttavat myös vähentämään ensisijaista DNS-palvelimen käsittelykuormaa. On suositeltavaa asentaa vähintään yksi ensisijainen DNS-palvelin ja yksi toissijainen DNS-palvelin kullekin DNS-vyöhykkeelle.
    • Vain välimuistiin tallennettu DNS-palvelin – Useless välimuistiin tallennettu DNS-palvelin suorittaa useless kyselyjä ja tallentaa nämä kyselytulokset. Siksi kaikki useless välimuistiin tallennettavaan DNS-palvelimeen tallennetut tiedot ovat useless tietoja, jotka on tallennettu välimuistiin, kun palvelin suoritti kyselyt. Useless välimuistiin tallennetut DNS-palvelimet tallentavat tietoja useless, kun kyselyt on ratkaistu. Tiedot, jotka vain välimuistiin tallennetut DNS-palvelimet tallentavat, ovat nimitarkkuustietoja, jotka se on kerännyt nimiresoluutio-kyselyjen kautta. Vain välimuistiin tallennetut DNS-palvelimet eivät isännöi vyöhykkeitä eivätkä ole mitenkään DNS-verkkotunnuksia varten.
    • Grasp-DNS-palvelimet – DNS-palvelimet, joista toissijaiset DNS-palvelimet saavat vyöhyketietoja DNS-hierarkiassa, kutsutaan master-DNS-palvelimiksi. Kun toissijainen DNS-palvelin on määritetty, käyttäjän on määritettävä pääpalvelin, jolta se saa vyöhyketiedot. Alueen siirto mahdollistaa toissijaisen DNS-palvelimen saada vyöhyketiedot konfiguroidusta ensisijaisesta DNS-palvelimesta. Toissijainen DNS-palvelin voi myös siirtää vyöhyketietonsa toisille toissijaisille DNS-palvelimille, jotka ovat sen alapuolella DNS-hierarkiassa. Tässä toissijaista DNS-palvelinta pidetään pääpalvelimena muille toissijaisille toissijaisille DNS-palvelimille. A secondary DNS server initiates the zone switch course of from its specific grasp server when it is brought on-line.
    • Dynamic DNS Servers – Windows 2000, Home windows XP, and Home windows Server 2003 computers can dynamically update a DNS server’s useful resource data when a shopper’s IP addressing info is added or renewed by means of Dynamic Host Configuration Protocol (DHCP). Each DHCP and Dynamic DNS (DDNS) updates make this attainable. When dynamic DNS updates are enabled, a shopper sends a message to the DNS server when modifications are made to its IP addressing knowledge. This means to the DNS server that the shopper’s A kind useful resource document must be up to date.

    Understanding the WINS Server Position

    The Home windows Web Identify Service (WINS) server roles provide identify decision providers for shoppers that have to resolve IP addresses to NetBIOS names and vice versa. A WINS server is an enhanced NetBIOS identify server (NBNS) that Microsoft designed to resolve NetBIOS pc names to IP addresses. WINS can resolve NetBIOS names for local hosts and distant hosts. WINS registers NetBIOS pc names and stores these shopper identify registrations in the WINS database. The registrations are used when shoppers question for host identify decision and service info and to resolve a NetBIOS identify to an IP handle. Shoppers which are configured to make the most of a WINS server as a NetBIOS identify server (NBNS) are referred to as WINS enabled shoppers. If the WINS server resolves the NetBIOS identify to an IP tackle, no broadcast visitors is shipped over the network. Broadcasts are only utilized if the WINS server is unable to resolve the NetBIOS identify. A WINS enabled shopper can communicate with a WINS server that’s situated anyplace on the internetwork.

    Since Windows 2000 was the first Home windows working system the place NetBIOS naming was not required, customers may nonetheless need to offer help for NetBIOS naming if they’ve conventional purposes. Keep in mind that all Windows working methods prior to Home windows 2000 require NetBIOS identify help.

    To implement WINS, just one WINS server is needed for an internetwork. Nevertheless, implementing two WINS servers offers fault tolerance for identify resolution. The secondary WINS server can be used for identify resolution if the main WINS server is unavailable to service WINS shoppers’ requests.

    A WINS server can deal with 1,500 identify registrations and roughly four,500 identify queries per minute. It is suggested to have one WINS server and a backup server for each 10,000 WINS shoppers. When the WINS server position is configured, the WINS server have to be statically assigned with the following TCP/IP parameters: static IP tackle, subnet mask, and default gateway.

    Understanding the DHCP Server Position

    DHCP is a service and protocol that runs on a Windows Server 2003 operating system. DHCP features at the TCP/IP protocol stack’s software layer. One of the main duties of the protocol is to mechanically assign IP addresses to DHCP shoppers.

    A server operating the DHCP service is known as a DHCP server. The DHCP protocol automates TCP/IP shoppers’ configuration as a result of IP addressing occurs via the system. Users can configure a server as a DHCP server so that the DHCP server can routinely assign IP addresses to DHCP shoppers without guide intervention. IP addresses which might be assigned by means of a DHCP server are considered dynamically assigned IP addresses.

    The DHCP server assigns IP addresses from a predetermined IP tackle vary(s) referred to as a scope. A DHCP scope might be outlined as a set of IP addresses that the DHCP server can allocate or assign to DHCP shoppers. A scope accommodates specific configuration info for shoppers that have IP addresses which are inside the specific scope. Scope info for each DHCP server is restricted to that exact DHCP server only and isn’t shared between DHCP servers. Directors configure scopes for DHCP servers.

    The DHCP server’s features are to:

    • Dynamically assign IP addresses to DHCP shoppers.
    • Allocate the following TCP/IP configuration info to DHCP shoppers:
      • Subnet mask info
      • Default gateway IP addresses
      • Area Identify System (DNS) IP addresses
      • Home windows Web Naming Service (WINS) IP addresses

    Customers can improve the availability of DHCP servers through the use of the 80/20 Rule if they have two DHCP servers on totally different subnets. The 80/20 Rule is applied as follows:

    • Allocate 80% of the IP addresses to the DHCP server on the local subnet.
    • Allocate 20% of the IP addresses to the DHCP Server on the distant subnet.

    If the DHCP server that is allotted with 80% of the IP addresses has a failure, the distant DHCP server would resume assigning the DHCP shoppers with IP addresses.

    With Windows Server 2003 DHCP, three options are available for registering IP addresses in DNS. The choices may be configured for the DHCP server or for every scope. The choices that may be specified to allow/disable the DHCP service to dynamically update DNS data on the shopper’s behalf are:

    • The DHCP server could be configured to not register any DHCP shopper’s IP tackle when it assigns IP addresses to these shoppers.
    • The DHCP server might be configured to register all shoppers’ IP handle every time they receive IP addresses from the DHCP server.
    • The default choice leads to the DHCP server registering the IP addresses of shoppers with the authoritative DNS server based mostly on the shopper’s request for an IP tackle.

    Understanding the Streaming Media Server Position

    The streaming media position offers media providers in order that shoppers can entry streaming audio and video. The Home windows Media Providers present media providers to shoppers. The Home windows Media Providers might be configured on server and enterprise platforms.

    The Windows Media Providers usually are not out there in the following Home windows Server 2003 edition:

    • Home windows Server 2003 Net Version
    • Windows Server 2003 64-bit versions.

    Understanding Certificates Authorities (CAs) Servers

    A Certificate Authority is an entity that generates and validates digital certificates. The CA provides its personal signature to the shopper’s public key. Through the use of the tools that Microsoft present, customers can create an inner CA structure inside their group.

    A digital certificates associates a public key with an proprietor. The certificates verifies the owner’s id.
