Since you've run into this twice, I would troubleshoot it rather than just
disjoining and rejoining the PCs. If there's a configuration or other issue
behind this, you're just putting a band aid on it until it happens again.
I'd start by checking the event logs on the workstation (system and
application). Troubleshoot or post back on any errors. Then when this
happens, check all your network connectivity - can you ping server to
workstation and workstation to server, using both name and IP address. If
you run an ipconfig /all on the workstation, is everything correct (post it
or compare to a properly working PC). Are group policies applying properly
on the client PCs (application log or open a cmd prompt and type "gpupdate
/force," watch for errors, then when it completes check system and
In what context are you getting the error you posted? At startup, login,
