Okay, two IP address under one name or two names pointing to the same
IP address?

That's DNS. But you said your PC's were getting allocated the same IP
address. That's not DNS.
Check the client PC for TCP/IP settings. If it's static, check both
to make sure you have two separate IP addresses. Actually, check if
it's dynamic as well. At a command prompt on the client do a IPCONFIG
/ALL and look at the IP addresses and see how they are assigned (is
there a DHCP server).
If the IP's are different, remove both IP addresses in your DNS
server. If you use dynamic IP registration in your DNS, do not add
them again. If you do not, manually add an A record for each system
name with the correct IP. Turn *everything* off and back on again.
Check the IP's on the clients. Ping the IP address. Then ping by
name.
