We begun experiencing a few issues accessing a mapped network drive late in the day after we rebuild a computer that had an OS crash with XP.
We just had to restart the PC in order to "re-establish" the connection because we received the following error:
"F"\ is not accessible.
The system detected a possible attempt to compromise security. Please ensure that you can contact the server that authenticated you."
And the only option was to click "OK".
Why would we have an authentication issue? We have not previously encountered this error, at least not in recent memory. To the best of our knowledge we are are not doing anything differently that would cause a connectivity issue.
