My current Terminal server has a collection previously setup on it. Everything was functioning correctly. One day I went into server manager to publish a new remote app into the collection however the Collections option found under Remote Desktop Services is no longer listed.
Everything on the server is functioning correctly. There are no error logs in the system or application logs. All the end users can still connect via remoteapp and launch their previously published apps. However I can no longer add any additional apps due to not being able to see the collection.
When navigating to the overview, it just gives me a notification that the Remote Desktop Services Deployment does not exist in the server pool. I have looked everywhere to see if anyone had any assistance in this issue but so far I have not had any luck. One user just reverted the system image and another user gave hint that it was an issue with DNS which I have checked.
