Has this ever happened to anyone? It has happened to me and one of my customers in the past but I have no idea how he diagnosed it and it is happening with another one of my clients now. The application runs, but the HTTP requests do not. The application works 100% perfect on my own computer but not the customers. He has both the 1.1 and the 3.5 framework installed, and uses Vista (same as me).

Can anyone shed some light on this situation because this is a huge huge huge problem that I would rather not have to worry about in the future with other clients. ANY help is greatly appreciated. Thank you in advance.
