Account-confusion

It seems i have one additional account beside my restricted and administrator-accounts.

i call them:
....X restricted -Account
....XA Administrator-account

In restricted account when i enter
cmd
i see this third account.
....x_2
in admin.-account i see:
....X
I am totally confused now.

these are also the directories i see in
dokumente und einstellung(german)
dont know the english word

2. beside this i wonder about the admininstrator-account i see when starting in safe mode. How is this called?
Thanks

Update
2. In safe mode its more confusing.

I see two accounts named:

administrator pass needed
......XA No pass needed
---------------------------
setting cmd in command-line i see
....X-2
confused now.

Maybe this third account was created automatically when i had to delete a corrupt one.
Thanks

Yes, XP makes a Admin account. So boot to safe mode and take a count Step 3 in the link.

In Safe mode at start i see:
Administrator with PW

....XA Cannot set PW
--------------------------------
IN Administrator-Account I see
Administrator PW set
....X retricted account PW set

In Safe Mode, you should bee able to set or change the passwords.

If you can not, something is real wrong.
