There are some problems with ArcGIS Desktop 10 connecting to ArcGIS.com through a proxy server. These issues are addressed in ArcGIS Desktop 10 SP1, which is due out shortly.Hi all. I just downloaded and applied the service pack and ... no luck. Still get the same error. Whats unfortunate is that there is no indication as to what site its attempting to access so I cannot test it through a web browser.
