Two things to check here Ang... 1) If the PNAgent site is located on an internal Web Interface server, configure the PNAgent site NOT to use a Poxy. Alternatively, ensure you configure proxy exclusions for the Web Interface server. Going through a proxy can come down to a timing issue, which can be flaky at times. 2) Ensure that the PNAgent URL for the Web Interface server is added to the IE Trusted Zone. Although I think your issue is more related to the proxy. Cheers, Jeremy.

I receive the following error: The remote server failed to execute the application launch request. Please contact your Administrator for further details. followed by Citrix online plug-in could not contact the server. Please check your network connection. I can confirm the Citrix Web Client works fine on the same machine. I manually changed the PNAgent server to use the secondary WI Server same issue so the issue is not with the WI Servers as it occurs on both. Other clients run PNAgent just fine. I uninstalled and reinstalled 11.2 client - same issue. I uninstalled V11.2 then installed V12 client - same issue. Ive seen this on a few clients and we ended up rebuilding the workstations. Would be great if I can find a solution. Any ideas? Thanks Ang ________________________________ Meet local singles online.
