[Full-disclosure] Undeletable user account.

[James Bower]

Hi all, one of my servers has recently been compromised.  No suprise but the 
hacker created himself a user account.  The problem is that I can't seem to 
delete the account.  The account is not part of any group.  When you look at 
the account it and go to Member Of it doesn't show anything.  When I try to 
delete it as the local admin I get an error saying that "An error occured 
while trying to delete the user"  "The user does not belong to this group.'  
I've tried adding the account to every group I can think of and then trying 
but I still get the same error.  Also this is a stand alone Windows 2000 
Server thats not running Active Directory.  Anyone ever seen this before?  
Thanks,
