Can no longer see the domain from Win 7 machine

Posted on 2011-10-31

I recently added a second Windows 7 Pro machine to our network.  Or Domain controller is a Windows 2003 Standard system.  We also have a member exchange server.  Today, the user of the new Win 7 machine was having some difficulties seeing the mapped network drives.  They just weren't there.  After looking at the machine closer, the login script was not running (which map's the network drives).  I then realized that I couldn't even "see" the network shares on the computer when I tried to access it via the run command (\\servername\sharename).  I could ping the server name, but under the "Network" icon, the computer could only see itself and not any other workstation or server on our domain.

I tried running the Network ID wizard again to re-join the domain, as it appeared it was no longer a member of the domain, even though it said it was.  When running the Network ID wizard, it kept saying the network location cannot be reached.  I made the computer back into a workgroup computer, removed the computer account from active directory, and tried to re-join the domain again.  Still the same problem with the message "The network location cannot be reached...".  I have another Windows 7 machine that has been working fine for almost a year now, but this one doesn't seem to even see the domain, even though it's getting an ip address from the Domain controller, which is also the DHCP server.  Any ideas?

    On your DNS Server, do you have any Tombstoned machines?  I would start by looking there..  On your Win 7 client, it is connecting into a W2003 domain?  Could also be running into a problem with conflictng IP Addresses..

    I just compared the NIC properties on the "good" windows 7 machine and the problem one.  The problem one is missing the "Client for Microsoft Networks"!  I added it back in, and now I can re-attache to the domain.  I have no idea how that vanished, and the users swears he didn't remove it.

    ...  and the users swears he didn't remove it.

    the user shouldn't even have the rights to do so ;)

    but that are the ways of the bits and bytes
