Our users have IE 7 and 8. We keep them locked into place by pointing IE to our firewall product (tools > internet options > connections > lan settings), so that only approved sites are the ones that our people can access.
In the last few days, several of them report issues with specific websites loading very slowly - load times of over an hour just to get the log-in screen to appear.
1.) Unchecked the "use proxy server for your LAN" under the IE menus
---> Site resolves instantly, as it should
---> This pointed me to the direction that perhaps the site wasn't configured for our firewall
2.) Re-checked the "use proxy server" box, and specifically configured the site in our firewall
---> Site continues to resolve slowly, with the same load times as before performing step 1
That would normally indicate that the problem is on the vendor's end. Something may be wrong with their site. And that's the line of thought I was pursuing until I was reported back to that the users are having the same problem on other websites. These new websites they're having problems with are, and have been for a long time, configured properly in the firewall.
I'm not sure what my next step is to pursue. What am I looking for now? I don't know enough about networking to figure out where to track next.
