Saxman,
In the dialog where you map a network drive, is there a
check box saying "Reconnect at logon" or something
similar? Make sure its checked.
If thats not it, maybe try to gauge how long your machine
spends trying to map the drive during login/reboot. Do
you get a message saying "Attempting to Map Drive X",,,
that hangs around? Or an error like "Unable to Map
Drive"? If so, at least you know your machine is trying
but the problem is it can't find the target. On the
other hand if your login just buzzes right by without
pause or error, the machine is probably not even trying
to reconnect.
Cut the problem space in half and let us know which side
you're on.
