Well this past weekend I took the jump and upgraded my domain controller to Windows Server 2003. No major problems...except for one with DHCP. For some reason the DHCP service no longer wants to bind to any network cards in the machine. Initally it wouldn't bind to the built in network card. Then another network card was installed and it bound to it no problem...clients started recieving IP's. But after a restart a couple of days later...DHCP no longer wants to bind to that one either. I have tried uninstalling and reinstalling the DHCP service. I have tried upgrading the network card drivers. I have AppleTalk installed on this machine and thought that might be causing a problem so that was stopped but with no success. The machine is a dell poweredge server with a broadcom gigabit ethernet adapter and an intel 8255x adapter. Has anyone had this problem or can anyone offer any suggestions. I'm at the point where I might just give up and turn one of my other servers into the dhcp server.
