One of our offices has a problem with a connection-specific dns suffix. Workstations are randomly pulling the wrong suffix. A ipconfig /release and /renew will correct the problem, but once the computer is restarted, it grabs the incorrect suffix. The suffix it should be using is 'marthaturner.cc' but it will grab 'plazahomemortgage.com' and we have no idea where it is coming from. We have removed the old DHCP server and put a new one in its place which didn't seem to fix the problem. Is there any way to find out where this phantom dns suffix is hiding. Any help would be appreciated.
