I have a Windodws 2008 R2 server that has been in production for over 2 years. It is a Hyper-V host running five 2008 R2 guests. Everything wasw running fine until a couple of weeks ago when I installed the latest HP firmware and drivers. Since then, Internet Explorer cannot open any website except www.google.com. After uninstalled IE9 and then installing IE10 there was no change. I've scanned the server with malwarebytes and HiJackThis. No problems found. I reset IE and reset the TCP/IP stack. No change. I removed McAfee AV and I'm now able to access google and one other site. I then installed Fiddler and looked at what is happening and it appears that most websites are trying to tunnel using port 443 rather than using the typical port 80. I'm not sure how to interpret this. I know name resolution is working and can ping the sites I'm trying to reach. If I go to a standard site, saywww.yahoo.com, the IE window stays blank but if I go to Tools/View Source it appears I'm looking at the HTML from the target site. Below is a summary of the Fiddler output when I tried to go to yahoo.com. Any help is greatly appreciated as I am all out of ideas.
Thanks,
Joe
