OK I tried adding it to the domain and it prompted me for a login and password. I put in the adminstrator and its password however a window came up that says "The Following error occurred attempting to join the domain "MELS"; Multiple connections to a server or shared resource by the same user, using more then one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again." I disconnected all shared folders and drives already connected to the server and yet it still comes up with the same error.
