I've been searching the web and Citrix etc. for the answer to this one but coming up empty. I think my search terms aren't correct, as I figure this has to have been asked before. I'm looking for a way to determine what devices have connected to a published app, for licensing. I know I can achieve this for all except CSG users by dumping all the devices (by clientname) into a text file at login, and then pulling the text files into a DB and removing duplicates, but I was wondering if Presentation Server (4.0) provides a mechanism for this. Thanks - Bob Coffman
