Hello all -
One of my clients has a network with a Windows Server 2003 machine setup as a DC with 12 client computers running XP Pro SP2. This past week, their server crashed and I had to replace the hard disk and reinstall the O/S. Fortunately, all of their work-related data resides on a slave drive which was unaffected.
After re-installing Windows Server 2003, I recreated as much of their old configuration as I could...i.e. same server name, same IP address, etc. I then ran DCPROMO and setup AD with DNS, DHCP and WINS (same as they had had previously). I used the same domain name that they had had, I recreated all the user accounts with the same names and passwords and re-established all the same file and folder permissions. I recreated all the shares from the server data drive as well.
Then I un-joined all the client PCs from the domain and rejoined so as to create the proper computer accounts and to give the domain users local administrative access to their PCs. After testing the logon of each user and finding it to be successful, I recreated their drive mappings to the shares on the server.
Everything is working pretty well BUT...every so often, some of the clients lose their ability to access the server shares through their mapped drives. When this happens, the following dialog appears on the workstation:
G:\ is not accessible
The system detected a possible attempt to compromise security. Please ensure that you can contact the server that authenticated you.
After that, any attempt to access the drive mapping produces this error:
An error occurred while reconnecting G: to \\Server\Share
Microsoft Windows Network : The local device name is already in use.
The connection has not been restored.
Only a workstation reboot will solve this problem. I have done a fair amount of research on this and have found a multitude of possible causes. I have already checked most of them (primarily having to do with DNS) and tried implementing a few solutions to no avail.
Does anyone have any idea of what I can do to finally resolve this once and for all? I am pulling my hair out at this point.
Thanks so much.
Chris
