I have three forward lookup zones in my DNS server. When I try pinging a server that's part of lookup zone A from a computer that's part of that same zone, I get a response. If I try pinging a server that's not in the same zone as the computer I'm pinging from, I get nothing. When I try an nslookup of the servers that are not part of the same lookup zone, the names resolve correctly. If I append the domain onto the name, I can ping it just fine.

Is there a way I can fix this? or do I need to keep appending the domain onto the name if the computer I'm trying to ping is not of the same domain as me?
