We are running Windows 2000 DNS servers with Windows XP Client machines. The clients are not resolving IP Addresses via DNS and are having to fall back on to legacy WINS resolution which is still in place for our small Windows NT 4.0 population. The correct DNS Suffix is being applied to the clients via Group Policies but when using nslookup with just the host name we achieve the following results: -
can't find xxxxxxxxxxxxxx: Non-existent Domain
If we provide nslookup with the hostname and the domain suffix however, the address is resolved.
Our Mac OS X clients resolve the address using just the hostname when using nslookup or host.
