The clients belong to two different companies that both utilize our TS on 2012R1. We have made no changes to the server in 3-4 months and this just started happening this week. It has happened 3 or 4 times that we know of. There are 300-500 clients on
the TS at any given time. Th TS client sessions are configured with a single startup program so they do not have access to the desktop.
