If you can't get it to work, I would suggest searching the MS website for the command. I'm sure they have a listing of the processes, and their language equivalents (most likely on the Dutch version of the site).
I tried that command, but the same error, Contact your system Administrator.. Mannn Administrator no longer exist... how can i tell this to bill gates A$$
You could send a letter to Bill, and if it actually reached him, he'd say "Gee...I need to give this to someone who actually has control over the software now."
see if you can find a program called ERDCommander2k online somewhere. It will let you boot into NTFS from CD and you can delete the folders I said before. Also, look into BartPE. It's very cool and I don't think it costs much...
or consider a rebuild. Might be time to cut your losses.
I guess i will try to copy ntuser.dat from some other XP based computer to that directory atleast it will have the rights.. of administrations, then i can always change the configuration.. after i load it to safe mode..
