In order to gain support for Windows 10, I recently upgraded our SEPM server to version 12.1.6 MP1. Upgrade appeard to go smooth. However, now the clients don't seem to be automatically updating definitions anymore, I have to manually 'run command' and 'update content' on my groups to push out the new definitons. And I think that only worked after I reconfigured the server settings to allow live update from the client and the internet. I did this because I kept getting bombarded with emails about my clients having out dated definitions.
So in other words, I'm pretty sure my clients are unable to get their definitions at all from the SEPM server which is how I've had it configured up to this point (prior to the upgrade). It seems I have to manually tell the clients to update, and even then they get their updates only from the internet (though I don't know how to verify this). Do I have to run some kind of client upgrade on each client or something for the new SEPM verssion to work as it should? Any ideas?
