DNS adding bad IP Address

[BrotherSnadir]

We're running Server 2003. I set the TCP/IP to manual and put it in an IP address and subnet and in DNS some reason it creates 2 HOST (A) records each having a different IP address for the server. One for the manual IP I assigned (x.x.x.100) and another out of no where (x.x.x.173).

Now my DNS shows two Host (A) records that show SERVER3 having IP address x.x.x.173, another Host (A) record for Server3 saying it's also x.x.x.100 AND Workstation45 also has a Host (A) record for x.x.x.173. People can't join the domain because it keeps sending them to the x.x.x.173 thinking that's where the server is when it's not.

How do I get rid of it? I first deleted the bad Host A record and it popped right back in. I then searched the registry and found that IP address hiding in HKEY_Local_Machine\System\ControlSet002\Services\TCPIP\Parameters\interfaces\{FAE323d...}\DHCPIpAddress so I chose to modify it and change it to a different network entirely and it immediately switched back. I then set the network card to get an IP address through DHCP and back to manual and rebooted. It's still comes back. Any ideas?

Does this server have a second network card that is using DHCP by any chance? Also check DHCP and delete that lease address for .173 and have workstatiion45 release/renew. Delete the A record for SERVER3 that points to .173
Hope this helps.

This appears to have fixed it. I went into the registry in HKEY_Local_Machine\System\ControlSet002\Services\TCPIP\Parameters\interfaces\ and saw 4 folders. I studied the other folders and looks like the one giving me the problem had more entries than it should, as if when I disabled DHCP it didn't clean up the registry. It had 18 entries, the other folders had about 6. I deleted the extra entries until it matched the other folders, rebooted, and that seems to have cleared things up.
