I spent a bit of time looking into a similar problem this past week.
The problem appears to be that if the Windows Shell or an application
attempts to access an AFS folder which requires tokens to access before
the tokens are available, then the drive map gets marked as inaccessible
in some way. The only way that I have found to make the problem go away
is to re-create the drive mappings.
Another similar problem is caused by the use of the High Security Logon
Option which attempts to use random user names when establishing the
SMB connection to AFS submounts without mapping them to drive letters.
In order for this to work it must be possible for the Windows OS to be
able to access the same network path via two different sets of credentials.
This is needed because the random user name and the current user name
are both used simultaneously. Windows 2000 appears to have trouble with
this scenario.
