Hey guys. I am using Windows Vista on the PC that is having this problem but I know the same thing happens on Windows XP Pro as well. What happened is I formatted a computer, installed the OS and then during install it asked me to put in a username for the person who is to be using the PC. I just put in "Tony" and specified a password. I got to the desktop, added the PC to our work domain and then added my network login to the PC. Now, under User Accounts there is "Tony", administrator of the local machine and "Aroberto", domain administrator. I removed the "Tony" account because the PC was to be used on the network and I didn't need this account anymore because aterall it was just a temporary name to get me onto the desktop after the OS setup. Now all I have is "Aroberto". I reboot, log in with "Aroberto" and then realized that I needed to take the PC out of the domain so cleared out our domain name and typed in "workgroup", rebooted and now I can't get onto the computer. I should have left the "Tony" account on there but I would think that you would still be able to get onto the computer somehow no?
