login on with network cable disconnected

Posted on 2005-05-09
Last Modified: 2008-01-09
I have a couple of Windows XP users (SP2) that can't logon to the network when the network cable is conected to their laptops. If they disconnect the network cable before they attempt to logon, then they can logon and after they get to the desktop, they connect the cable and do their work.
I can't figure out why they can't logon to the the network unless they first go through this process of disconnecting the network cable; can anyone help with this?

    There should be some error messages in the event logs of the affected laptops and on the domain controller. (if there is one of course)

    A shot in the dark: I suppose it's an authentication problem with the domain controller, but some more information about the network and the error messages will help a lot to troubleshoot your problem.

    You say”can't logon to the network” but it sounds more like local login in both case,
    Make shore computer is member in a workgroup not a domain.

    Is there a server in you network, you say “couple of XP users” is this local users or couple of computer, do you use login prompt or auto login.

    1.Try to login to Pc without the cable.
    2.then disjoin the pc from the domain (join the workgroup).
    3.shutdown the pc.
    4.go in the active directory -> computers and delete if there is any entry for that computer name.
    5.start the pc and join to the domain.
    6.try to login first with the administrator user account on that pc.
    7.if it works log off and login as that particular user.
    (see if you can login to any good and working pc with that user name)
    (check in the active directory in that user->properties->account->logon to > make sure all computers is selected.)
