Jack- I typically like Method A better, but it has its drawbacks. Some policy, such as you've discovered with security policy, can't be easily undone. For example, in your interactive logon message example, you can't simply set it to Not Defined in the higher precedence GPO to have it undo the message. You would have to set it, but leave it blank, in order to undo that message. So, maybe the best solution is a mix of approaches, where you only put settings that universally apply to all computers in a set of few master GPOs and then apply specific settings at the OU level linked GPOs, using security filtering if you need to isolate groups of machines or users for specific settings.

Method A 1. Creating a master computer GPO for all settings common to the majority of our computers. 2. Creating "exception" GP's with a higher precedence to turn off individual settings set in the master GPO not desired for specific OU's . Or... Method B 1. Creating many individual GPO's for the majority of our computer OU's. 2. Simply leaving off an individual GPO if it is not desired for those machines. Method A would seem to create fewer GPO's, but can we always rely on the ability to turn off a setting already turned on by the master? Method B would seem to create more GPO's with a more complex precedence order, but simplify troubleshooting. I have run into a problem with Method A; after turning on the Security Options Interactive Logon Message in one GPO, I am unable to turn it off again in an exception GPO higher in the precedence order. Input would be appreciated. Thanks, Jack The contents of this e-mail are intended for the named addressee only. It contains information that may be confidential.
