It is possible to establish a security context with another domain by using the net use command.

Syntax:

net use \\<server name>\IPC$ /USER:<domain>\<account>

Explanation:
If you want to manage the Booky domain, with a PDC called Kooky, and you had an administrative account on Booky called bookadmin, you could use:

net use \\kooky\IPC$ /USER:BOOKY\bookadmin

you will be asked for the password.

After you do this, you can see the IPC entry by typing “net use”.

This will allow you to administer the Booky domain, even if you are RASed in from home and authenticating locally.
