Our GPOs seem to be frozen in time.
What I mean by that is, if I change an existing GPO the changes don't apply to the affected users/PCs, and if I create a new one it doesn't even show up in the results from GPRESULT.
Yesterday I created a test GPO and applied it to a test OU which contains a test account as well as my own day-to-day account. When I run GPResult against either account the GPO doesn't show up at all. GPUpdate /force makes no difference.
However, if I run GP Modeling the new GPO does show up (albeit as Empty, which I'd expect because, you know, it's empty!), but not when I run the GP Results wizard.
Note also that some GPOs that have been in existence, and working, for years are not showing in the output from GPResult (but yes, they do still exist in the GP Management MMC).
We have no known replication issues (Spotlight on AD, and MS SCOM), It's like only a subset of GPOs are being 'delivered' to client accounts (User or Computer).
There are no processing errors in the client PCs' event viewer.
Can anyone advise what might be going on here?
