Everything I've searched for on this site seems to be 4+ years old and doesn't seem to work so I'm making a new post. We started getting reports last week of 50+ of our 200+ clients being out of date. When I log onto the clients to and run live update, the definitions all show current from the clients themselves. I tried deleting the cache (the agentinfo folder) on the SEPM side and rebooting the services and it brought up the same results. So far it looks like reinstalling the client "may" have worked, but I'm looking for a simpler solution first than having to touch each individual machine.
SEPM version is 12.1.6 build 7266 and we pushed the latest client, 12.1.7266.6800 through SCCM in June. SEPM is showing clients having definitions of around the end of September.
Attached is a debug log I ran on one of the clients.
