We have the following Setup:

2 Windows 2003 Server Domain Controllers
Each DC has 2 NIC Cards in.

1st NIC 10.x.x.x
2nd NIC 172.x.x.x

If you connect via 1st NIC then all is Ok, if however you change the computer's IP and connect via the 2nd NIC you get a warning and the following in the Event Log:

The name "COMPNAME :0" could not be registered on the Interface with IP address 172.x.x.xxx. The machine with the IP address 172.x.x.x did not allow the name to be claimed by this machine.

I have checked the DNS records and removed any that may cause a problem.

Does anyone have any ideas? All the workstations connect on the 10.x.x.x range, but I need another server to connect using the 172.x.x.x range.

Any suggestions appreciated,

Thanks Matt.
