We just upgraded a mandrake server and included was samba 3. All of the windows workstations had to be re-added to the domain. All were successful (XP & W2k) except a NT 4.0 box, which was successfully removed from the domain, but when I try to add it back, I get the error; You already have a connection to the domain. You must disconnect before rejoining the domain. Looking at the Network Identification, it is listed as workgroup named workgroup. How do get this machine back onto the domain?
