I was attempting to create a home network, and in the process I messed up my roommate's computer. I believe that I switched the settings from domain to workgroup, and then changed the workgroup name. I was then instructed to restart the computer, but now I cannot login to windows. When I type in her user name and password, I recieve a message telling me to make sure that the user name and domain are correct. I understand that the problem is that the domain is incorrect, but the login screen does not give me an option to play with the domain. I have read that I can login as an administrator so that I can fix the settings, but I have no clue how to login as an administrator, or where to get the password. My roommate's going to kill me. Help!
