I had to reconfig an ISA on a SBS 2003 and have everything working accept one workstation needs to upload a file through a website application. I have the website names whitelisted in the ISA client proxy config and also in the trusted websites at the workstation. There is no error message popping up it just hangs busy forever when it should be less than a minute.
I'd like to turn off the ISA for this one workstation to confirm the application does work and then know for sure its the ISA that needs configuring and then would like a procedure to find out what port number or credentials this hidden app uses. The vendor support says it should work fine and could not provide port number used or server info other than whats been white listed.
