A couple of days ago, I started getting HTTP 400 responses from all websites. Nothing will go across port 80. However, everything works if I connect to VPN. The weird thing is, without VPN, other things still work; such as IM and anything else that doesn’t use port 80. Pinging also works.
I haven’t noticed this behavior on any other computer on my network. The kicker is, if I log on as a local admin, everything works fine!!!
I haven’t installed anything in the last couple weeks and I don’t remember changing any configuration. I ran Forefront and HouseCall and neither found any problems.
