I managed to connect the PC to the domain(win Server 2003) and it worked fine for some weeks, the user went on leave foe two weeks, I logged on this machine with my administrator credentials while the user1 was on leave just once, to share the printer for user2 to print, when user1 came back she could not login with her passwords, i reseted her password with the mind that she has forgoten it but stll could not login, the domain admin too could not log in, the local admin managed to log in and all the internet services could be accessed through the local admin and the network map was there too..i could ping any address or server/computer name, I removed the machine from the domain, deleted the computer from the AD, unchecked the IPv6 but still the PC cannot be reconnected to the domain, i tried specifying the DNS address but still nothing, amazingly the local admin can still have some network resources, connects through my Proxy...

Hi, What error message did you receive when you add the pc to domain? Try to temporally disable firewall for test. Also the issue may be caused by the PC in AD is inactive.
