I recently added a new Win2008 DC that has the global catalog and is the only computer that will be the fileserver. However, I have an older computer running Win2003 that used to be the DC but still runs AD. The users network cards all point to the new Win2008 DC and its IP address. However, when I run nslookup, the user computers all show the IP of the old Win2003 computer. I tried manually to set the server to the new one on the command line on the user computer, but when I reboot the user computer, it always defaults to the old DC and its IP address. What I am doing wrong?
