Hi. We have a peculiar problem with IE accessing an intranet
application.
Many people access it thru the Remote Desktop connection to a terminal
server; they launch IE there and work with the app. Sometimes, about
once a week, a random user experiences the following:
Application stops loading. IE windows is white (about:blank) and
status shows loading indicator ar "detecting proxy settings..."
message, but nothing is in fact loading and IIS logs show gaps in that
user's access to the app, e.g. requests are not sent to the server.
Other applications that are situted on the same remote server work
normally.

As soon as you restart IE, the app (the one that was inaccessible)
becomes accessible again.

What can the problem be? We are pretty puzzled...

Hello? Anyone? Is there at least some way to diagnose a problem?
