Administrator is disabled. Help

[Gintaras]

Accidently I disabled administrator account and now I have just one user
guest account with limited privilegies. I know administrator's password but I
can't reenable it. How to reenable admin with guest account?
Windows XP SP2- NTFS

[Mark L. Ferguson]

Boot to Safe Mode (F8 struck repeatedly, during the 'black screen' after the
BIOS screen)
The default "Administrator" account usually has a blank Password.
User Accounts in Control Panel will add a new admin account.

I tried boot safe mode, but then nothing appears. no admin, no user, nothing

So, I must reinstall or repair winxp instalation?

Try hitting Ctrl+Alt+Del twice and see if you get a Logon box. Booting
on to the installation via the Recovery Console will also re-enable the
built-in Administrator account. If that fails there are free third
party reset utilities that can re-enable the account.

[John John (MVP)]

Don't bother with the Recovery Console, the information I gave is
incorrect, you will be able to logon but the account will only be
re-enabled for the RC session, it will be disabled again after you logoff.

Ctrl+Alt+Del on safe mode helped. I loged on like admin and reenabled it.
Thanks for all

You're welcome.

That probably means you are in Administrator mode... on my computer
there are no user accounts and I am alway the administrator.
