    Initially I created a new XP virtual pc using the same login and domain as
    the host pc and it connected fine to the network.
    Now all of a sudden at the windows login I now get "Windows cannot connect
    to the domain, either because the domain controller is down or otherwise
    unavailable, or because your computer account was not found. Please try
    again later. If this message continues to appear, contact your system
    administrator for assistance"

    There is a knowledge base article
    http://support.microsoft.com/default.aspx?scid=kb;[LN];318266 that refers to
    this message however the solution did not fix the problem.

    The strange thing about this is that I can log in using the local
    administrator account and if I then browse the domain network via windows
    explorer and attempt to access any of the resources on the network, I get a
    popup requesting domain\username & password which I then supply and I get

    So, everything was working. Now it isn't. This really doesn't sound like a
    VPC issue. Check to make sure you haven't changed the settings for the VM's
    networking (i.e., Shared networking (NAT), tied to the Host NIC, whatever
    you originally set). Since you can access the network from the VM, I don't
    think this is the problem.

    There isn't enough information in your message, so I'm not sure why you
    singled out KB 318266. The error message you specified is common. There are
    lots of knowledge base articles about issues that cause this message to
    come up.

    Do you have any other VMs with the same problem? Or that work?

    The networking setting has only 1 network adapter which is set to the
    network card the host uses.
    The message is what stopping me from logging onto the domain so that is all
    I can go by.
    The knowledge base I was referring was the closest match to the environment
    I am in i.e XP client connecting NT 4.0 Domain.
    You may be right in saying it may not be a VPC issue however I log the host
    using the same credentials without a problem and I expect the VM to do
    This is the only VM I have created so I don't know if creating a new one
    will fix the problem.

    Beyond the network setting for the VM, all of the rest is configuration
    within the Guest OS. As you stated in your original message, your VM
    does have network connectivity, even to the server where you are
    experiencing the connection problem. This points to an OS-related issue,
    not VPC.

    You might try one of the OS support groups for further help.

    Are you using undo disks for your XP VPC? If so, then what has likely
    happened is that the password used for the secure communications channel
    between the XP client and the domain has been changed (which occurs
    automatically). If you use undo disks, the problem is that the password
    change occurs, then you dump the changes, and you're back to the old
    password. You can confirm this is the case by removing the XP computer
    from the domain, and then rejoining it. If that works, then that was
    likely the problem. There are a couple of KB articles about this issue.
    Try searching the KB for DisablePasswordChange.
