We have just upgraded all of our workstations to the 4.91 Client and are
having problems with mapped drives. Users are able to login without any
problems but then they get an error in the login script saying access
denied. After the error sometimes it will attach to another server and
map sys and public and other times it won't map any drives at all. The
biggest problem is that it does not map user’s home drives. This problem
is not consistent on any machine and happens randomly. Sometimes
restarting the computer once fixes it and others need to be restarted 3
or 4 times. We have recently updated to 4.91SP1 but that did not help.
