Incorrect display of User, Computer Hierarchy and Resultant Policies when viewing Remote Diagnostics information.
When viewing Remote Diagnostics information, the GPOs from the User and Computer OUs are displaying instead of just the User OU when expanding the user hierarchy.
The above issue is caused if the loopback processing is enabled on one of the GPOs. If loopback processing has been enabled in 'Replace' mode it will result in the User hierarchy displaying the same GPOs as Computer hierarchy even though it actually has different set of GPOs. However, if it has been enabled in 'Merge' mode then it would result where user hierarchy displays GPOs from both User and Computer OUs instead of just the User OU node.
NetIQ GPA RSoP feature provides support for "Loopback Processing". View the Reports of all the GPO's that are displayed on User and Machine Hierarchies. Look under the GPO settings section to validate if "Group Policy Loopback Processing mode" setting has been enabled in Merge or Replace mode. If it has been enabled on any of the GPOs , the system behavior, as described in the symptoms, is valid.
