    upon running an audit on one of my networks Retina 4.90 discovered two 
    systems, running windows 2000 pro, with sp3 and all updates with what 
    appeared to be multiple administrator accounts.
    snip ---
    Accounts: User: Administrator Pass: rotartsinimdA - Account password 
    reverse of account
    Accounts: User: Administrator Pass: Administrator - Account password same 
    as account
    Accounts: User: Administrator Pass: - Account with no password
    snip ---
    However the system shows no evidence of these accounts in the user 
    manager...  but the accounts are there.
    i can connect to the system using my specified Account and password... AND 
    the three above.
    Only these two machines have ghost accounts that i know of,  due to my 
    network setup i do not think anything has owned these to machines just 
    yet... i checked my traffic logs and nothing has left these two machines 
    over the network.
    
    
    I've never seen this before and was wondering if anyone knew anything than 
    might help me figure out what has cause this and
    1.) how i can remove these ghost accounts? (they don't show up under the 
    user manager)
    2.) how would i be able to find other ghost accounts since Retina only 
    scans for default accounts?
    3.) How can i DISABLE the administrator account in 2k? (i get an error 
    message when i try and disable it that the account can not be disabled)
    
    All help is appreciated
