We have a bunch of thin clients that are running Windows 7 embedded with the write filter active on them. We have the CCM, CCMcache, CCMsetup folders, and the smscfg.ini file excluded so when things are written to these the changes are applied. We are currently running CM 2012 R2.
For a months these systems will be running fine, and then out of the blue they will start showing Inactive and they seem to stop talking to the server. When you look at the client activity it will show the devices haven't talked to the server in a long while. Eventually they switch to showing the client isn't even loaded anymore on the device.
If you look at the thin clients the sccm client seems to be running fine. The only way to get the device to start talking to the server again is to stop the SMS host agent, delete the smscfg.ini file, and then start the service again. We have around 300 thin clients and I can't keep doing this manually.
Does anybody have an idea of what might be causing these systems to go into this state?
Thanks in advance for any ideas
