I am a little confused by my results in nslookup. If I do:
Default Server: ny-XXX.XXXnet

> ny-it-intel233
Server: ny-XXX.net

Non-authoritative answer:
Name: ny-it-intel233.XXX.XXX.net
Server: ny-XXX.XXX.net

Name: ny-tr-teacher.XXX.com

How do both pc's come with the same IP? What do I need to do to fix this?

RE: Nslookup

In the first case you're doing a forward lookup and in the second one you're doing a reverse lookup. The naming doesn't have to be one to one. A machine may have multiple names with one IP or multiple IP with one name. I believe the reverse zone has to list one name to IP, even if the machine has multiple names (hence multiple entries, one for each IP). Generally if you query the name you will get all of the IP addresses listed, but in the reverse lookup you will get the one name.
