I also see only "Dr" in the drive listings of both the afscreds systray
tool and afs_config.exe.

In our networked Windows/AFS architecture we still use a global drive,
however we have been planning (for quite some time) to migrate away from
it. The historical reason we use a global drive is because Windows needs
access to the network folders that contain the users roaming profile data
.... before the standard user drives are mounted (post profile). I have
done some preliminary investigation by changing some profile paths for some
test users AD profiles to using UNC paths. The results were not good. If
memory serves me (I did this investigation over a year ago), the problem
was that Windows handles client side caching and access control differently
than a "drive mount". I seemed to be continually bombarded with file
sychronization popups when UNC paths were used. This may have been more
related to our use of "folder redirection" than the profiles themselves. I
have not had the time to get back to performing the tests with the current
AFS client. That's on my list.
