I am applying a logon GPO to a Computer OU (with only computer objects within), when I edit the policy using User Configuration the GPO shows up when doing gpresult -r but when I edit the policy using Computer Configuration it doesn't show up when doing gpresult -r (previously doing gpupdate/force). Any idea why is this happening and how to fix it?
I'm not 100% sure, but this might help you:
In the Group Policy Microsoft Management Console (MMC), click Computer Configuration.
Locate Administrative Templates, click System, click Group Policy, and then enable the Loopback Policy option.
Try Merge Mode
For the group policy object (GPO) in question, I suspect that the "GPO Status" might be set to "Computer Configuration settings disabled" currently, and hence the computer configuration (despite editing) is not coming into picture after group policy update!
Please confirm that for the said GPO, the "GPO Status" is set to Enabled (as shown in the below screenshot), for allowing both User Configuration and Computer Configuration to come into effect. Please try after doing a fresh group policy update.
