    Is it likely this person busted my account password and then signed
    onto my machine using my account?  I saw in my security logs where
    he connected ten times using NTLM authentication and I read about an
    old exploit over at Microsoft's technet site talking about how a hole
    in NTLM could allow an attacker to bypass domain authentication, where
    a login gets disabled after 3 incorrect attempts, and use a brute force
    password cracker to bust the password in the credentials file.  It said
    the attacker would only have access to the host machine and not other
    domain resources.
     
    I downloaded the patch to fix this but it said the patch was for systems
    on SP1 and I'm on SP3.  I haven't installed the patch for fear it will
    hose my system but I have changed my password to a real strong one.
     
    Thanks
