We've had a rendering server running for over a year now. It has been great. It was running 2015 up until this morning.
Last week (before the upgrade) we had problems with the server and I rebooted the box. Then I loaded up the render server and set it to the watch folder.
Immediately, the progress starts saying the render control file not valid for ... for several waiting projects.
We tried re-collecting the data and several other things and that didn't work.
I then noticed the designer is running 2015.3 and the farm was on 2015. So, I upgraded her this morning. Tried again and still getting the same errors.
What can I check to determine how to fix this problem?
