Suddenly my ability to browse disappeared yesterday. I can still ping by ip/name, I can connect to RDP computers remotely. I also have a virtual machine on my laptop that is able to browse the web.

Firewall is off. It feels like my port 80 blocked. I did sfc check but it didn't help me at all.

This happened when I was my VPN client FrontiClient.

Found the answer to this issue but have to wait for 10 more hrs to post it here as unswer:) The issue was with the settings for the proxy in IE. Somehow they got changed yesterday. –  Timka Sep 15 '12 at 14:05

And finally found the 'cause' of this:) (ah, took me 8hrs to figure it out) - I was using fiddler and didn't noticed that it crashed, therefore proxy settings in IE didn't revert back to default='no proxy' –  Timka Sep 15 '12 at 14:11
    
please do post it as an answer –  Sathya Sep 16 '12 at 13:06

After spending most of my night/morning trying to figure out the issue by applying different 'fixes' I found the problem:

Somehow my IE's proxy settings were on with the details below: 'http' proxy was set to 127.0.0.1 port 8888 'Secure' was set to 127.0.0.1 port 8888

And 'do not use proxy' list was set to: <-loopback>

After disabling proxy my issue was resolved. The program responsible for this 'switch' was Fiddler. For some reason it crashed (without me noticing it) and left the settings on.
