On my previous post, I had a chance to take on Group Policy Preferences with a very quick very humble description of it. On our part 2 we will demo on "How to manage local administrator accounts on machines" which has been a one of the favorite topics on the web before, even at the Microsoft Philippines Community Forum way back 2007. Before what we do is create a script to do this and run thru GPO, now with Windows Server 2008 Group Policy Preferences, we can do it in just a few clicks.
I also chose that the local built-in administrator cannot change its password and it never expires. You can also chose to disable it if you want to. In order to assign a new password to it, fill up the Password and the Confirm password. Apply or click Okay and there, you have successfully deployed a GPO that updates Built-in Local Administrator and its passwords for all of the machines that this GPO applies to.
If you have not visited my first post, here is a link for more info on Group Policy Preferences.
