You will need several pieces of information from the second computer you are trying to connect to. One is the actual computer name (host name) of the computer. The second is the administrative user name and password. When you map the drive you will want to map it to \\computername\c$ then check the box that says "Connect using different credentials". For the user name you will want to put computername\adminName then in the password ***** you will type in the password.
