Problem mapping remote drive

Archived from groups: microsoft.public.windows.server.general,microsoft.public.windows.server.networking,microsoft.public.windowsxp.work_remotely (More info?)

I have configured an employee's machine to connect to the office network via
a vpn connection. However, when I attempt to map a server drive to the
user's machine, I click the "Connect using a different user name" option and
supply the credentials which works okay - but then I am presented with
another username/password dialog to connect to the server.

How do I overcome this problem?

Thanks in advance,
