in reply to NET USE to map drive with specified account & password

NET HELP USE produces more detailed information than NET USE /?

The syntax you seek is something like:

NET USE x: \\jones\backup YOURPASSWORDHERE /USER:DOMAINNAME\james
Note - NO Space between "USER:" and the name.

For greater security, replace YOURPASSWORDHERE by "*" - this will prompt you for a password.
