Group Policy Query - Applying an enabled GPO with no settings defined.

Hi all,

I have just discovered a policy that has been applied (Probably by a previous member of staff) to an OU that is showing as applied in RSoP but has no settings defined.  Both the Computer and User configuration sections are enabled but have no settings.

This is applied in the middle of the set of policies that are being applied.

What will be the effect of this?  Can you think of a reason why this has been done?

I am thinking that it has absolutely no effect but it may be that it resets ALL preceding GPO settings to undefined and then all subsequent ones do apply as normal.

Please can someone advise me on this?  I have done a search on the web but can't find anything as guidance for this eventuality.

Thanks.

If there are indeed no settings defined in the GPO, then its application will have no effect at all (except for an increase in GPO processing time).
This might have been a test GPO where the setting(s) configured have been removed again after testing.

Hi oBdA,

Thanks for the quick reply.

I need to be absolutely sure of this as I will be making a change to our live environment and hundreds of users will be affected.  Can you provide any evidence to back up you statement?

I hope you understand why I need to be sure.

Many thanks.  I really appreciate the help here.

That's how Group Policy works; if there's noting defined, there's nothing to do (and I doubt you'll find any documentation explicitly stating this).
An empty GPO will especially not reset anything that has been done before, and neither will it have any influence on whatever happens after. You can only undo changes from a GPO applied earlier if you explicitly set the policies.
I've been working with Group Policies since their release with Windows 2000 AD (and NT4's System Policies before that), so I like to think that I know what I'm talking about.
