Computer security Question:

Microsoft recommends that you changes the name of the administrator account so that outsiders cannot guess the name.

This is of course just one of the things you can do. But unlike what some Microsoft employees believe, security does not stop there. Just changing name of administrator is to trying to protect yourself by the lowest level of security there is, security by obscurity .

It is possible to obtain the new name of the administrator by using the command
nbtstat -A <ip-address>
when the administrator is logged in on the console.
