Windows Server 2003

Windows Server 2003 (also referred to as Win2K3) is a server operating system produced by Microsoft. Introduced on April 24, 2003 as the successor to Windows 2000 Server, it is considered by Microsoft to be the cornerstone of their Windows Server System line of business server products. An updated version, Windows Server 2003 R2 was released to manufacturing on 6 December 2005. Its successor, Windows Server 2008, was released on February 4, 2008.

Released on April 24, 2003, Windows Server 2003 (which carries the version number 5.2) is the follow-up to Windows 2000 Server, incorporating compatibility and other features from Windows XP. Unlike Windows 2000 Server, Windows Server 2003's default installation has none of the server components enabled, to reduce the attack surface of new machines. Windows Server 2003 includes compatibility modes to allow older applications to run with greater stability. It was made more compatible with Windows NT 4.0 domain-based networking. Incorporating and upgrading a Windows NT 4.0 domain to Windows 2000 was considered difficult and time-consuming, and generally was considered an all-or-nothing upgrade, particularly when dealing with Active Directory. Windows Server 2003 brought in enhanced Active Directory compatibility, and better deployment support, to ease the transition from Windows NT 4.0 to Windows Server 2003 and Windows XP Professional.

Changes to various services include those to the IIS web server, which was almost completely rewritten to improve performance and security, Distributed File System, which now supports hosting multiple DFS roots on a single server, Terminal Server, Active Directory, Print Server, and a number of other areas. Windows Server 2003 was also the first operating system released by Microsoft after the announcement of their Trustworthy Computing initiative, and as a result, contains a number of changes to security defaults and practices.

The product went through several name changes during the course of development. When first announced in 2000, it was known by its codename, "Whistler Server"; it was then named "Windows 2002 Server" for a brief time in mid-2001, before being renamed "Windows .NET Server" as part of Microsoft's effort to promote their new integrated enterprise and development framework, Microsoft .NET. It was later renamed to "Windows .NET Server 2003". Due to fears of confusing the market about what ".NET" represents and responding to criticism, Microsoft removed .NET from the name during the Release Candidate stage in late-2002. This allowed the name .NET to exclusively apply to the .NET Framework, as previously it had appeared that .NET was just a tag for a generation of Microsoft products.

Microsoft Domain Name System (MDNS)

Microsoft DNS is the name given to the implementation of domain name system services provided in Microsoft Windows operating systems.

The Domain Name System support in Microsoft Windows NT, and thus its derivatives Windows 2000, Windows XP, and Windows Server 2003, comprises two clients and a server. Every Microsoft Windows machine has a DNS lookup client, to perform ordinary DNS lookups. Some machines have a Dynamic DNS Update client, to perform Dynamic DNS Update transactions, registering the machines' names and IP addresses. Some machines run a DNS server, to publish DNS data, to service DNS lookup requests from DNS lookup clients, and to service DNS update requests from DNS update clients.

The server software is only supplied with the server versions of Windows. I want to share my experience with DDNS and Computer Help.

DNS hosting service

Dynamic DNS is a service that runs Domain Name System servers. Most, but not all, domain name registrars include DNS hosting service with registration. Free DNS hosting services also exist. Almost all DNS hosting services are "shared"; except for the most popular Internet sites, there is no need to dedicate a server to hosting DNS for a single website. Many third-party DNS hosting services provide Dynamic DNS and Computer Technical Support.

DNS hosting service is better when the provider has multiple servers in various geographic locations that minimize latency for clients around the world.

DNS can also be self-hosted by running DNS software on generic Internet hosting service

Free DNS

A number of sites offer free DNS hosting, either for second level domains registered with registrars which do not offer free (or sufficiently flexible) DNS service, or as third level domains (selection.somedomain.com). These services generally also offer Dynamic DNS. In many cases the free services can be upgraded with various premium services

Configuring Logging for the DNS Server

There are several categories that log messages fall in to. For instance, all queries fall in to the "queries" category, all notify messages will fall in to the "notify" category, and so on. We are interested in the "dnssec", the "update" and the "security" categories.

The messages for every category are channeled into files or through syslog. The channel phrase can be used to specify which severity level should be logged, how the format of the log message should be, what extra information should be logged, where it should be logged, how many versions should be kept, and how large the zone file may grow.

For this setup we will log all above categories in one place:

logging {

    category dnssec   { security_log; };

    category update   { security_log; };

    category security { security_log; };

    channel security_log {

        file "dns-security.log" versions 5 size 20m;

            // every time the log grows over 20 Mbyte, it will

            // backup and rollover. Maximum 5 backups will be kept.

        print-time yes;

        print-category yes;

        print-severity yes;

        severity info;

    };

};

This Blogs Help to work with Dynamic DNS. I want to share here with you is my experience of sharing the DNS Server Configuration and providing a computer support assistance. The most common use for this is in allowing an Internet domain name to be assigned to a computer help with a varying (dynamic) IP address

DNS works in theory

Short for dynamic Domain Name System, a method of keeping a domain name linked to a changing IP address as not all computers use static IP addresses. Typically, when a user connects to the Internet, the user's ISP assigns an unused IP address from a pool of IP addresses, and this address is used only for the duration of that specific connection. This method of dynamically assigning addresses extends the usable pool of available IP addresses. A dynamic DNS service provider uses a special program that runs on the user's computer, contacting the DNS service each time the IP address provided by the ISP changes and subsequently updating the DNS database to reflect the change in IP address. In this way, even though a domain name's IP address will change often, other users do not have to know the changed IP address in order to connect with the other computer.

How DNS works in theory

The domain name space

The domain name space consists of a tree of domain names. Each node or leaf in the tree has one or more resource records, which hold information associated with the domain name. The tree sub-divides into zones. A zone consists of a collection of connected nodes authoritatively served by an authoritative DNS nameserver. (Note that a single nameserver can host several zones.)

When a system administrator wants to let another administrator control a part of the domain name space within his zone of authority, he can delegate control to the other administrator. This splits a part of the old zone off into a new zone, which comes under the authority of the second administrator's nameservers. The old zone ceases to be authoritative for what goes under the authority of the new zone

DNS servers

The Domain Name System consists of a hierarchical set of DNS servers. Each domain or subdomain has one or more authoritative DNS servers that publish information about that domain and the name servers of any domains "beneath" it. The hierarchy of authoritative DNS servers matches the hierarchy of domains. At the top of the hierarchy stand the root nameservers: the servers to query when looking up (resolving) a top-level domain name (TLD).

DNS resolvers

A resolver looks up the resource record information associated with nodes. A resolver knows how to communicate with name servers by sending DNS queries and heeding DNS responses.

A DNS query may be either a recursive query or a non-recursive query:

• A non-recursive query is one where the DNS server may provide a partial answer to the query (or give an error). DNS servers must support non-recursive queries.
• A recursive query is one where the DNS server will fully answer the query (or give an error). DNS servers are not required to support recursive queries.

The resolver (or another DNS server acting recursively on behalf of the resolver) negotiates use of recursive service using bits in the query headers.

Resolving usually entails iterating through several name servers to find the needed information. However, some resolvers function simplistically and can only communicate with a single name server. These simple resolvers rely on a recursive query to a recursive name server to perform the work of finding information for them.
