When browsing (IE and Firefox) internally, externally, and on the server itself, https://remote.***.com/remote
takes over 60 seconds to load. Once loaded, everything is fine.
Other internal websites such as http://companyweb
load quickly, so no problem there.
Have imaged server and recreated issue on test rig, different hardware so unlikely to be a hardware specific problem.
SSL certificate is from Geotrust.
As I am using a test rig now, no other computers are attached so the server is not suffering from excessively high memory or cpu usage.
Spec of test rig server is:
Windows Small Business Server 2008 64 bit (fully patched and AV removed for testing purposes)
Processor Intel core 2 duo 2.66GHz
Researched this lots but have struggled to find anyone with the exact same issue.
