DNS slow name resolution

I have a DC running Server 2003, SP2 with the Active Directory and DNS role.  When I ping itself by name, the response is instant, but when I ping another server/machine on the network, it takes like 5-8 seconds to resolve the name and then the ping is successful.
If I ping from any other machine on the network, the response is instant, just not on my DC/DNS server.

Any thoughts?

it could be the dns naming order, on the workstations, are you able to post an ipconfig from the server and workstations, plus the command you are using to ping? Are you using a FQDN or just the machine name?

Are you pointing the DC at itself via its real IP address or its Loopback address?

I figured it out -- I did an ipconfig and found that there were DNS suffixes in there that don't exist, so it seems like it was timing out with those before resolving locally.
Thanks for the help.
