PENDING ConfigMgr Clients Inactive Obsolete

[day79]

We have a ton of ConfigMgr clients that are showing they are on, but "inactive". Clients haven't sent their heard beat or inventory in several days...see attached pic. These machines have been powered on all week. They aren't able to install software from Software Center or take deployments. We recently upgraded to 5.00.8968.1000 and installed a hotfix. Any suggestions on what to check? Management Points all look good. Reinstalling the client appears to work but there are tons. We do use Sophos AV and recently tried Endpoint out before deciding to stay with Sophos. Sophos rolled out a new version and we added the following exceptions:

C:\Windows\CCM
C:\Windows\CCM\*.sdf
C:\Windows\CCM\ServiceData
C:\Windows\CCMCache
C:\Windows\CCMSetup
C:\Windows\CCM\Logs
Any help would be appreciated!

Check the inventoryagent.log to see when they last performed inventory.

Well that is telling you the answer.

Sorry, I'm not the usual ConfigMgr admin. Things just aren't working and saw polling was back in 7/1 when the computer has been on all week. I guess I'm misunderstanding

You need to dig deeper as to what the "real" problem is. What change around July 1? Is it all clients or some?
