I have a Windows 7 computer that was joined to domain XYZ and I accidentally ran sysprep without first removing it from the domain. I had the following options enabled - OOBE, Generalize, and Quit. After that I restarted the computer and the computer was no longer on the domain, but was now in workgroup XYZ. I changed the workgroup name to WORKGROUP. Then I tried to rejoin domain XYZ, but I am getting a message that it can't find the domain controller. I need to rejoin it to the domain, how can I do that?
