I tried to add my work laptop to a workgroup (see attached image from where I did it. Note that this image was taken from my home PC where I am on a workgroup, and I just put a sample domain in the image).
Didn't ask for a password or anything. When I rebooted, I could not log on. Turns out I was removed from the company domain, and the username/password required to log on was that of the original individual who images the laptop.
IT tells me there is no way to add me back, and my only recourse is to reimage the laptop!
Is there any options? The harddrive is encryped, however, I have obtained the encryeption key and could access it now from another PC.
