What have I done?

[BriPriUK]

Hi
I'm getting a log-on screen asking for a password when I turn on my PC even though I've never had a password ( XP Pro) and when I turn off I get a drop-down menu with options instead of the three Turn Off and Restart buttons.
What have I done, and how do I put it back to how it was?

Windows update?

Have you tried to join a domain? Sounds like that.

Not deliberatly, but if I have how do I un-join it?

You can check whether it's this or not by going CONTROL PANEL > SYSTEM > COMPUTER NAME. It will tell you there.

Steve, Thanks a lot for the link. Somehow I'd set up a Netware client account. God knows how - must have been p*ssed.

Cheers
