I realize that there is a similar thread in the forums about this already, but I have tried recreating the collections as suggested in that thread and it didn't solve the issue, so I'm asking the question again. I had one of my connection brokers crash today and since that time, all of my collections are showing an unknown status:
I am able to interact with the collections through PowerShell and the desktops appear to be functioning correctly, insomuch as users can connect to them without issue. However, they aren't listed under the Collections node in Server Manager and I can't manage them from Server Manager. This is a production system so I can do anything too crazy to test or fix it without some planning, but I was hoping that someone has experienced this issue (apart from the person in the aforementioned thread) and has a good solution for me.
My environment is Windows 2012 R2.
