I have an OU named "Asia" wherein I've set regional settings via a GPO named "Asian Settings." This GPO is linked to the "Asia" OU and the link is enabled. However, when I run gpresult the log indicates that the "Asian Settings" GPO was NOT applied nor was it filtered out. I've tried gpupdate but that didn't resolve the problem. Can anyone explain why the GPO is not being applied to the OU and what I need to do in order to have it applied?
With loopback processing enabled (in replace mode) it tells the GPO CSE's to process and apply the user settings defined in the GPO linked to the TS OU instead of processing the user settings defined in the GPO linked to the user OU (Asia). I suspect the loopback setting is configured to replace the user settings and not merge the user settings.
In addition, setting the loopback policy to merge mode would process and apply the user settings from both the computer and the user OU's.
Did you try gpupdate /force, or just gpupdate? If the latter, it may not happen right away. The default wait time on gpupdate is 600 seconds or 10 minutes.
