A connection attempt failed problem

[Dennis]

I'm getting the following problem occasionally...the application will
work perfectly well for a period of time and then this pops up.

I have tried turning off the default proxy in the web.config which I
had seen on other posts but that did not solve the problem.

Any assistance or ideas would be appreciated
Thanks

Looks to me like the Weather service just didn't respond. Not much you can do
about that.

When I get the "connection attempt failed" message from the application
running on server...i get it repeatedly...during the same period if I
browse directly to the external site (www.weather.gov) it responds
correctly. Eventually the problem on the server will clear and the
application displays correctly.

I don't really think its an issue of the external site being down....

thanks for responding
