ArcGIS for Server 10.3 is creating a \arcgisserver\directories folder on our C: drive even though all our ArcGIS for Server Directories are set to the D: drive. If I delete it I find that it reappears in a few seconds. When I first installed 10.3 the \arcgisserver\directories\arcgissystem\statistics folder was in the C: drive. I also noticed that when I started the Search service the \arcgisserver\directories\arcgisjobs\utilities\search_indexer_gpserver was created in the C: drive. I have changed Server Directories back and forth, rebooted, and searched registry and directory for "C:\arcgisserver" but was still unable to resolve the issue.
