We have a load balanced terminal server farm using session broker and DNS round robin to connect. We push the applications out to the users via a Sharepoint webpart. Every so often we get an error in the event log that reads:
No programs were detected on FARMNAME.local. Ensure that the server is an RD Session Host server and that it is online.
Everything i have read about this points to something in the farm not being able to talk back to one of the servers, but i've checked everything is pointing at the load balancer, and there are no duff dns entries. Its not happening all the time, but it does seem to be happening more and more.
Anyone any ideas what i can look into?
