Built-in Administrator Account - Enable or Disable

I know this is a very old thread but it popped up when I had the System Error 5 problem so I'm posting this for future reference if someone else has the same problem.

I tried everything I could find on Google but nothing worked - the I saw I had 2 domains on the PC and I was logging onto the wrong one with the Administrator PW - that's why it seemed that my Administrator account was deleted.

I picked it up by going to Manage Users - Users - then I viewed the list of users (of which administrator was one) and I saw the domain read something different as to the one i was trying to log on to.

I switched user, typed in DOMAINNAME\Administrator (no PW) and VOILA! I could do what was needed to do.

I hope this helps someone somewhere that also gained gray hairs of struggling with this problem

I tried Options 1, 2, 3. I keep getting "Access is denied"

I couldn't even complete Option 4!

Please help!



Some details about what happened:

I accidentally deleted the domain administrator from my computer!

I am logged into my computer using a local user, which has no administrator privileges. Then, I logged in as the domain administrator, and was trying to remove the domain administrator as being the only one in charge, but I didn't know that that meant I would be removing all administrators! :/

I went to MANAGE USER ACCOUNTS (from User Accounts in Control Panel) and saw two users, and thought that by deleting both, that would be fine.

DUMB MISTAKE!

Now I can't make ANY changes to this computer because it has no administrator!

THANKS FOR THE QUICK RESPONSE!

Haven't gotten around to Method II! I meant to try that tomorrow. I tried Method I, and when I typed in "list volume", it gave me some error (which I didn't record down).

If Method II does not work, is there no other way?!

There has to be SOME way to be able to add/remove users or remove the computer from the domain!

ok i finally got it typed right and i think accepted how can i check to make sure?
