We just installed a new SBS2000 server with the ISA
application. We are using a desktop application that does
a get command to obtain a file via a URL the application
specificies. The app hangs at the splash screen for 5
minutes before it opens and the request does not process.
If you manually take that URL and put it directly in IE
you can get to that location without a problem. Our IE
LAN settings are defined with our proxy server at port
8080. If I deselect the proxy server settings in IE and
launch the app it opens right away; no waiting for 5
minutes. I reselect the proxy server settings and reopen
the app at it opens right away, even with the settings
reselected. I cannot figure out why the application is
prohibited from getting the updated file via its URL but
not when you take the same URL and do it manually within
IE. Desktops are XP.
