Looking into an issue where a fairly important policy that published trusted sites failed to load on a decent number of client machines (I believe mixture of Win7/XP). End users were getting errors on internal apps that depended on those trusted sites being in place. This seems to have happened for about 15-20 minutes but it caused a fairly large ripple. I am trying to troubleshoot and haven't found much. A colleague was working on another policy which he originally thought may have been a factor but the settings involved aren't applicable and they tested loopback processing in merge (not replace) mode.
On one DC I found two repeats of a 1085 Group Policy Error that fell into the time frame but I can't find any info out there on this message: Windows failed to apply the ConfigMgr User State Management Extension. settings. ConfigMgr User State Management Extension
