Proxy error when launching applications

This issue is driving me mad and I can't seem to get my brain around what I may have done.

We have Citrix Presentation Server 4.0 running on a Windows 2003 server. Our web proxy is Symantec Web Security 3.0. At some point, I must have stuffed things up because, when you attempt to launch an application from inside, an error is returned saying the "Proxy connection failed: The configured proxy server failed to establish a connection." When I turn off my proxy settings in my browser, things work fine.

Any assistance on this would be GREATLY appreciated!

Ask the Experts


are you launching apps from a web interface or just using Program Neighborhood?


Program Neighborhood internally.

I have a few clients that are using the web app to connect via VPN but I have them connecting via IP address rather than host name and it works fine.

My end goal is to offer the Citrix apps via Secure SSL to remote users and Program Neighborhood to those internal. Currently - remote users are using VPN to connect (not my preference but it works for now).

At this point - I just need to get Program Neighborhood working again...




As you can likely surmise - I am a Citrix newbie. I've been at this job now for only two months and am a lone administrator looking after 90+ clients and 13 servers. Needless to say, I have not had time to do much with this installation. That said -

I finally discovered the Access Suite and (after digging around for about an hour) worked out Greyend's suggestion to turn off proxy for the PN users. IT WORKED!!!

I love this forum! It's been worth every cent paid.
