I have an XP Pro Box SP-2 with an Administrator Account and a User Account as well as a (Backup Administrator Account for Emerg Situations)
Recently I went into the users accounts on this PC to just change the login pictures, as Fast User Switching is enabled. While I was there I noticed that the Backup Admin account was not configured as either a Limited User or Administrator so I enabled it as an Administrator. The next day I started this computer up and noticed that only the Limited User account and Backup Administrator where the only accounts available, so I login and yes that is all that was there all traces of the Main Original Adiminstrator Account were gone. So I used the back up Admin Account to do a system restore to the day before this change, so all is well again. But then when I login to the Original Admin account and look at the users accounts the backup admin account is not configured as Admin or Limited User again. So I enabled it again as Admin and rebooted….As soon as the system rebooted, same situation the Original Admin account is gone. I did another System restore and left the Backup Admin account as a unconfigured account.
Why is this happening..??? I have never ran accross this before, has anybody else??
