In the last 2 days, I been connecting by the Computer Management console to every single Nt/2000/Xp computer in my domain. I rename the local administrator account and change it password. I also rename the guest account and I had a very strong password. I was so suggest to create an account with guest as username with a very strong password and to disable it after.

So basically, I had a NT guest account disable and now, I have a guest account rename with very a strong password and a new account with the username "Guest" with a very strong password.

Why does having a new account with the username "Guest" with a very strong password help when you allready rename it? Auditing who try to log with it that account?
