We have two Windows 2008 R2 servers that we use for agents to log into to access our customers systems. Saturday morning we received complaints that on both servers the web is running horribly slow. This happens on all websites and the majority of the time the web site times out trying to load.
Other users located at the same site but using their desktop machine do not see any issue. We have rebooted the boxes and checked settings and cannot find the cause. The CPU/Memory/Network/Disk Space use on the server is very low. I thought it might have been a MS update causing the issue but it appears the last update was applied in January.
We have rebooted both boxes and I am in process of trying a different browser. Any ideas what could be causing this?

I recommend you RDP into servers and run Network Monitor while trying to browse the slow sites and see if you get retransmits, syn retransmits, etc.
Also narrow your issue by trying non HTTP protocols out to Internet and see if it's just web browsing.
If your using a web proxy that would be a place to troubleshoot as well.
