Good morning, and happy Friday everyone. I'm running into a strange problem here with pnagent. I'll try to break down the situation as best as possible. The problem is, users RDPing into a terminal server (Win2k, XP clients), then using pnagent for their published apps. We have pass-through authentication set as the only choice in the config file, and it is set as default. When a user logs into the TS, they are prompted with a login box. If they right-click on the pnagent icon and choose properties, the Logon Mode field is blank. Clicking the drop-down shows the pass-through authentication option, but if that is selected, it does not work. It will disconnect them when hitting OK, then if they try to reconnect, the login box comes up, and if they go back into the pnagent properties, the Logon Mode field is blank again. Their pilot environment is 2 load balanced WI4 servers on Win2k3 SP1, 3 load balanced Win2k terminal servers, and 4 MPS4 servers on Win2k3 SP1. Now here's where it gets strange. Local XP clients work fine with pnagent. A user (admin or normal user), can login directly to the console of one of the terminal servers, and pnagent works fine, but if they RDP into the terminal server, even using the same userid, pnagent behaves as above. I've been through the Citrix KB article CTX368624 (troubleshooting pass-through authentication) as well as the articles it references. I've tried various forms of the client install, including a pre-packaged one created here that works fine on XP desktops, and the latest from Citrix's site. I'm running out of ideas here, so if anyone has seen anything like this, or has any ideas, it would be greatly appreciated. Thanks!
