We have the Remote Console published in Citrix and recently made it available for more tech's to use. When we did this we found an issue with Remote Control via Citrix.
Only one person can use remote control at a time when in the Citrix console (by right clicking a device and selecting Remote Control). If another person is using it, or if for some reason the issproxy.exe process hung, other remote control sessions don't work.
We've contacted LD support, but their canned answer is that "Citrix is not supported". 
Our citrix box is 2008 R2. Not real sure of the citrix version, but I can find out.
Does anyone else use a Citrix or TS console? Have you run into this and do you know if there are any work arounds?
