I am running Windows Server 2008 with Windows XP clients. About a week ago any computer that was rebooted started coming up with a "Duplicate Name Exists on Network" error. This happens on all PCs when they are rebooted. I've tried:
unplugging a PC from the network
leaving the domain and joining a workgroup
booting up in the new WORKGROUP and changing the computer name
rebooting then plugging the PC back in and I get the "duplicate name..." error immediately
This is a network of only 12 PCs so I know there aren't any duplicates. Any ideas?
I've figured it out. Since it kept happening even after I changed the computer name I decided this wasn't an AD issue but a NetBios issue. I threw a packet sniffer on the network and every time a PC booted
