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!
