I am having an issue with dns lookups. The setup it a bit complex, so I will explain here briefly. We have a product called "Campus Manager", it basically switches around client machines to different VLANS based on if you have antivirus and MS updates installed. The two VLANS where users are placed initially are for registration and remediation. The "Campus Manager" box is a linux box with their application running on it. Its has a standard dhcpd and named install on it to service the two VLANS. The named config will only allow it to go to certain domain names, and in the zone file all the domains are forwards to the Active directory name server we have running. The issue that I am having is that while on these two VLANS I cannot perform an nslookup properly unless I put in a trailing period. For example,

nslookup will produce
and the IP of the VLAN interface on the Campus Manager box

nslookup will produce
and all the IP's that it resolves to

Not sure whats going on, any help would be appreciated....
