Scenario: A Citrix Architect identifies a fault in the Active Directory design for CGE's existing XenApp environments. Group Policy Objects (GPOs) from OUs across the Active Directory apply when end…

Loopback processing in "merge" mode combines user GPOs from the computer's OU with the user's native GPOs, which might not provide the "full control" desired as unwanted settings could still merge.

Configuring loopback processing in "replace" mode at a GPO linked to the root level (or a high-level OU encompassing all XenApp servers) ensures that only user policies defined within the computer's OU (or higher in the computer's path) are applied. This effectively ignores user policies from the user's native OU, providing full control and preventing undesirable GPOs from applying.

Configuring loopback processing in "merge" mode at the regional level still combines user GPOs, failing to provide the complete override required for full control.

While "replace" mode is correct, applying it only at the "regional level" might not achieve full control if XenApp servers exist outside that specific regional OU structure or if there are other GPOs linked higher up.
