on Win2k3 with PS4, WI 4.2, and ICA client 9.2 I am seeing some weird session sharing issues. With a pnagent site configured for regular pass through authentication with an explicit name and password, the user launches a published desktop, the pnagent runs on that desktop, they get their apps and when the launch them, they launch from that server nice and fast. Session Sharing works and all is well. When the user connects to the same published desktop with a smartcard (CAC for you DoD guys) they connect to the published desktop, the pnagent loads, and when they launch the app, they do not session share and they start a nesw session, sometimes on the same server, sometimes on a different server. After that, the apps share from that session but never from the original one. Has anyone seen this before or have any thoughts about it? Since it works with a name and password, i believe the apps are all set correctly for color depth and options etc. I double checked and they are good. Greg
