The problem occurs when working on sitecore content editor. When a user takes some action, internet explorer freezes and after a while it shows
ReadResponse() failed: The server did not return a response for this request.
When I am connected to our hosting servers through VPN connection it works fine. Any help in debugging this is greatly appreciated.
