Question : 10.0.0.3 address on 192.168.1.x network

I have a server 2003 network with Windows XP clients.  After successfully adding a workstation to our domain, the workstation's ip address shows 10.0.0.3.  The workstation shows up in the Active Directory.  It also shows up in the DNS console but with an IP address of 10.0.0.3.  All of my other workstations are 192.168.1.x.  

I  have tried ipconfig /release, ipconfig /renew on the wokstation and ipconfig /flushdns, ipconfig /register DNS on the DNS server (which is also our AD server.)  If I try to force the ip address through TCP/IP protocol, I can't ping it (Request timed out), nor can I ping the 10.0.0.3.

Please help.
 

Answer : 10.0.0.3 address on 192.168.1.x network

ok

have a hunt round the building for a wireless router or other network device that's been plugged in - oh the joys of finding a rogue dhcp server

actually, the workstation that has the address 10.0.0.3, what is the IP address of the DHCP server or default gateway for that workstation?  try typing that address into a browser on the workstation and see what comes up.  for example, if the default gateway is 10.0.0.138, type that into a browser and see what comes up.
