Pass through authenication

I have remote users that have machines that have an
established account on our domain. They take their
machines home, logon with the same credentials that they
used when connecting directly to the network, then VPN
into the network over their high speed connection. They
have access to everything on the network but can not map a drive to a share.
If we use their credentials with the
net use command with the option [/USER:[domainname\]
username] it works fine. It seems as though the pass
through credentials are not working. Why would this not
work? How can I correct this problem? We have just a
small amount of users having this problem. Others users
that have the same image but are using other ISP's are
working fine and are able to map without a problem. The
user that I am talking about is using the Microsoft PPTP
VPN client which works fine for everything but mapping a
drive. These are windows 2000 and NT 4.0 workstation
users. We don't seem to be having a problem with XP
users.

When the users take their machines home, they do a local login when they
boot up, not a domain login. So the credentials they present to access
domain resources after connection will not be their domain credentials. The
only way I know around this (apart from the net use ... /user: you mention)
is to log into the domain at connection time using the login using a dialup
connection option.

XP has a modified credentials manager which does send the correct domain
credentials when you are connected remotely.
