I'm in the middle of a PDM Link test migration and have ran into a problem with our proxy server. When I try to log onto our PDM Link test server, I get an error 504 page not available. When I go to my IE connections tab and uncheck the proxy server settings, everything works fine.Our IT dept. saysas long as the settings are set to bypass the proxy server for local addresses everything should work...yeah well, it doesn't. The PDM Link consultants think it's our problem, IT thinks it's a PTC problem. Needless to say, I'm caught in the middle. I'm at a loss on this...some one give me an idea.
