A GPO is Linked at the Domain level that controls IE7 Trusted Sites Zone content via User Configuration settings but does not seem to be processing correctly to all domain accounts. Why?

We have a W2K3 Domain in Native mode. OS is W2K3 Srvr Ent. SP2 with R2. There is a GPO that is linked at the Domain level with ENFORCED enabled. The primary function of this GPO is to control the contents of the Trusted Sites Zone within IE7 via the User Configuration settings within the GPO. Within the GPO, some Computer Configuration settings have been configured however; the entire Computer Configuration settings section has been disabled. The trusted sites were implemented via the Site to Zone assignments list within the User Configuration\Administrative Templates\Windows Components\Internet Explorer\Internet Control Panel\Security Page\Site to Zone Assignment List and assigned a value of 2 which is supposed to add them to the Trusted Sites zone within IE7.

My problem comes from the fact that, on several server class machines within my domain the GPO appears to be applied (seen via the gpresult output) but in actuality the settings do not take place.

I have attempted logon with several different accounts that have Domain level administrative credentials and each reports via gpresult that the settings have been applied and yet when I go to check the contents of the Trusted Sites Zone, the assigned sites from the GPO are not there.

The exact same accounts have been used on other server and workstation class machines and have worked appropriately.  

I am completely at a loss for how to proceed forward in the troubleshooting train.

Any help is appreciated.

hmm try not clicking ENFORCE and tick the LINKED box...and link it to the computers/groups/users within your domain..

also check to see if they have the policy applied or the GPO and then click on the delegation the bottom left is a button for advanced.. click that and then this will show u all the users/groups and if they have the policy applied or denied  (this is at the bottom of the list i think)

In this situation, ENFORCED will eventually be required. For now, I have removed ENFORCED and Linked the GPO to the OU where the user account lives. This has resulted in the output of the GPRESULT now showing that the GPO has been applied twice and yet, it still doesn't work.

I checked the delegation tab per your instructions and the Domain Administrators group has Full Control (including Read and Apply) to the GPO. The account I am loggin onto the server in question with is a member of the Domain Admins group.

I have arrived at a solution through my own troubleshooting.

It appears as though my culprit is the Internet Explorer Enhanced Security Configuration component. Apparently, as I stated in my original problem description, the GPO settings were being delivered (As witnessed in the gpresult output) but the IEESC was filtering out the settings. From the looks of things IEESC takes control after your desktop has been initialized, and thus after GPO processing has completed, and then IT controls what settings you get.

The IEESC component has 2 pieces. The settings for Administrative users and the settings for Other Users. Simply removing the Administrative settings piece, caused things to begin to function as I intended. This was done via Control Panel/Add Remove Programs/Internet Explorer Enhanced Security Configuration/Details.. then unchecking the Administrative Users piece.

Thank You to all who offered their support.
