In developing an application at work, I've found that recently my Application won't update - even if it is set to check before the application loads, and even if I had set a minimum application version. It will work fine, when I take it home and behind my own personal firewall. Talking to the city IT administrators is like talking to a brick wall. You pretty much need to have presidential clearance before they change anything. ANy ideas on what I can do or what ports need to be opened or cache's cleared for this to work?
