Windows 2000 Administration in a Nutshell

Name

DNS server

Synopsis

Clear the server cache, configure a caching-only name server, configure a forwarder, configure scavenging, monitor a DNS server, specify boot method, and update server datafiles.

Procedures

Administration of DNS servers is performed primarily from the DNS console (see DNS for general information about this tool). This section covers general tasks associated with DNS servers. For tasks relating to zones and zone files, see zone in this chapter. For other general tasks relating to setting up DNS on your network, see DNS in this chapter.

The procedures assume that you have opened the DNS console by selecting:

Start → Programs → Administrative Tools → DNS

Clear the DNS Server Cache

Right-click on DNS server → Clear cache

This removes all resolved names from the server cache. The server cache contains information received from other name servers in response to recursive queries it has issued.

You might clear the server cache after you manually modify existing resource records within a zone (for example, if servers had their IP addresses changed). This will ensure that DNS clients querying the server will have names resolved from zone data and not from a stale server cache.

Tip

The server cache on a DNS server and the resolver cache on a DNS client are two different things, although both are present on a DNS server (since every DNS server must also be a DNS client).

Configure a Caching-Only Name Server

Simply install the DNS Server service on a Windows 2000 server, and ...
