Checked the events on the connection broker?
User is selecting the right pool and is entitled correctly?
any luck for the issue mentioned.we are also facing the same issue..
I would be really grateful if someone auggestsa fix..
The only time we get that issue is if there are not enough available desktops in the pool. The user obviously is entitled to said pool or they wouldn't get that far but there may be no available desktops to pick from. Is this a dedicated or floating pool?
