  • Microsoft DNS
    1 a. Domain Name Service (DNS) encompassing Microsoft DNS From Wikipedia, the free encyclopedia Jump to: navigation, search Microsoft DNS is the name given to the implementation of domain name system services provided in Microsoft Windows operating systems. Contents [hide] 1 Overview 2 DNS lookup client o 2.1 The effects of running the DNS Client service o 2.2 Differences from other systems 3 Dynamic DNS Update client 4 DNS server o 4.1 Common issues 5 See also 6 References 7 External links [edit] Overview 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 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. [edit] DNS lookup client Applications perform DNS lookups with the aid of a DLL. They call library functions in the DLL, which in turn handle all communications with DNS servers (over UDP or TCP) and return the final results of the lookup back to the applications. 2 Microsoft's DNS client also has optional support for local caching, in the form of a DNS Client service (also known as DNSCACHE). Before they attempt to directly communicate with DNS servers, the library routines first attempt to make a local IPC connection to the DNS Client service on the machine.

When you need to communicate with a remote machine, you usually do so by typing the machine name into the client software or command. DNS is then interro- gated by your system to discover the IP address of the remote system. Once that address has been obtained, your system can initiate communication through auto- matic and standard networking techniques. DNS extends beyond your organization, because it’s normal for your DNS servers to be configured to communicate with DNS on the internet and hand off the reso- lution of queries they can’t handle.
