I am having an issue with some of my Windows 8.1 clients. After awhile the client will go inactive, if I log into the machine and try to restart the SMS agent host service it hangs at stopping. I have to force stop it using the PID and then start the service again. The client will work for about a day and then go inactive again. I have tried looking through the logs but do not see any errors that would help me solve this.
I am on SCCM 2012 R2 with SP1 and CU1. Client version 5.00.8239.1203
