I am trying to resolve a problem with a 2003 sbs machine, everything would appear to be working on the server, all clients seem to be working ok, when i do an nslookup on the server i receive
***can't find server name for address XXX.XXX.XXX.XXX Non-existant domain
default server:unknown

Any ideas how I resolve this or what implications it has for the network

set up a reverse lookup zone for your subnet

It happens if there is no PTR record for the name server's IP address, create the reverse lookup zone like crawfordits mentioned and you should be all set.

You can find RFC1035 at which explains DNS in detail.

If you havn't setup your reverse lookup zone yet, you'll need to do that prior to adding the PTR record.  This link will outline how to setup the reverse lookup zone, then at the bottom it tells you how to add the reverse zone PTR record.

I already put in a reverse lookup domain the problem was it takes a while to enter the records in itself, I checked a few hours later and did an nslookup and it all works perfect.
