Thank you for answering my question.
Yes, I have verified and tested all of those and more. :-) I have been
looking into this problem for a couple of weeks now and have found other
developers with the same problem in old news groups. Some of them only
experienced the problem on their local machines and among them some could
identify [EMAIL PROTECTED] or other distributed computing clients as the cause of
the problem, others had to format and reinstall OS and everything else...
As for myself, I have tried my application on my own computer (Win XP
Pro), on our test server (Win 2k Server) and one of our production servers
(Win 2k Server) with the same result: WebException: "The operation has
timed-out." If I run my app over and over on the same 50 URLs, the URLs
working and the ones resulting in time-outs are different ones from time
to time.
I think it is strange that Microsoft has no information on the subject
since this strange behaviour has been reported by several users since
early 2002.
