I am having problems getting a Windows XP machine to join a 2000 server domain. The rest of the computers are running either XP or 2000pro and they are on the domain. This one was upgraded from win98. The machine is getting assigned an ip within the range that the dhcp on 2000 server is set to assign. Any ideas on why this machine might be having a problem while other XP machines are not. Thanks in advance for any help.
