Rename the Windows Administrator User

For Windows Server 2008

Learn how to change the name of the default Administrator to prevent brute-force password attacks.

The Administrator is the default user for all Windows Server operating systems and almost all brute-force password attacks will attempt to gain access as this user. While you may be able to set Account Lockout Policies for all other users, the Administrator user is exempt from these settings and can never be locked out. It is therefore suggested to rename the Administrator user and you can do so by following these steps.
