RemoteObject Troubles on Windows

Thanks to the other thread on here regarding the use of RemoteObject in AIR I have been able to create a great connection between my AIR app and a CF server.   At least, most of the time. I have a Flex-based AIR app that uses a RemoteObject that connects with ColdFusion to retrieve updates on the data stored in the AIR app. As I mentioned, this setup is working superbly when the AIR app is installed on a Mac. However, when the app is installed on Windows I receive the following error whenever trying to retrieve updates from ColdFusion: faultCode: Channel.Call.Failed faultString:'error' faultDetail:'NetConnection.Call.Failed: HTTP: Failed' The other twist on this issue is that it only occurs off campus. Working on a high speed university network, where the CF server is located, I can run the AIR app on either operating system and it works with the CF server just fine. My issue is with using RemoteObject with my AIR app installed on Windows running off campus. Any help in understanding this issue and/or how to fix it would be delightful. Thanks, Scott
