Hello I just had someone ask me to help with this situation. It seems all of a sudden session sharing stopped working in the Citrix Presentation Server 3.0 farm Currently there are 5 Servers in the farm. When they go to launch the second application it starts a new session and they can not share the applications between the sessions. This was working fine until a couple of days ago, naturally they told me nothing has changed in the farm. They have already gone through this article http://support.citrix.com/article/CTX159159 <http://support.citrix.com/article/CTX159159> . Apps are published with the same settings. Can someone think of any other troubleshooting advice for this? Thank you Brian Rota,
