I have and RDS 2012 deployment with one RDWeb Gateway server, 2 brokers and many hosts. Today we have had an issue where a few users from one particular child domain are not able to see any RemoteApp Icons when they log into RDweb.
Other users in the same domain (and same physical LAN) are able to see everything just fine. I logged into RDWeb on one of the users machines and was not able to see any icons either. From another machine, it worked just fine.
I have restarted the Web Gateway server and have the affected users using the remote apps through their start menu (no issues there). My steps are to have the users try from another known working PC and I am going to start RDWeb Tracing on the web gateway.
I did check the WMI security permissions on their terminal server and I see the RDS Remote Access Servers, RDS Endpoint Servers and RDS Management Servers in there as they should be. Any ideas?
