may be a place to start. Let us know if you find anything. If I have to deal with this, and I find a solution, and I remember, I'll let you know.
I did see this post but so far it hasn't 'cracked' the problem. Other information, such as WTSDomainName and WTSUserName, are being returned with information using the RD Web Client. It is the WTSClientName, which just so happens to be something we use, that is coming back empty. We will do some more digging.
