The following assumes that the machine is an AD domain member:
Connect to the machine remotely with Registry Editor. Open regedit on a remote computer, using alternate credentials if necessary. Such as Domain Admin credentials. In Regedit, click
File -> Connect Network Registry... and connect to the computer with the busted profile.
Since you say that there is only 1 profile on this machine, then it has to be Administrator (SID-500.)
So now that you are connected to the remote machine's registry, navigate to
And delete every subkey that looks like
Next, open up a Command Prompt, Cmd.exe, again using alternate credentials such as a Domain Admin, that has privileges on the remote machine. Run the following command:
C:\> rd /s \\computer01\C$\Users\Administrator
Delete the directory. Also delete any other similar directory like
\\computer01\C$\Users\Administrator.Domain if it exists. If this is Windows XP or 2003, the profiles will be under
Documents and Settings, instead of
Now, if this is not a domain-joined computer, then your only options are to do something like
- Hit F12 during boot and use the recovery options, such as
Last Known Good Configuration, or
- Use the Windows installation media (DVD, USB,) if you don't have a recovery partition, and use that to repair, restore from backup, etc. At the very least you can open a command prompt and copy off some files if you need to reimage the thing.
