Could not connect to certain websites in Windows 7

[deararis]

Since I upgraded my OS from XP to Windows 7, I could not connect to certain websites (eg. www.blogger.com) and some websites takes a long time to load (eg. Sign In). It's not my connection problem cause I tried the website on my other PC and it worked but not this one.

I also couldn't upload photos to facebook, twitter and other sites. I have tried opendns but no luck. I've also unchecked all on the 'Advanced JavaScript Settings' in Firefox. Also Windows Update keeps showing error '80072EE2' even after I have fixed it. Anyone know the solution to my problem?

As a test you could temporarily turn off the Windows Firewall and any security program you may be using.

Turned off windows firewall and disabled AVG linkscanner but still can't connect. On the tab, it says 'connecting...' and at the bottom it says 'transferring data from www.blogger.com....'

I believe Windows Update still uses IE to for access to the Microsoft updates. I once had a mysterious problem where I could not log in to another PC which normally presents a login screen, so I finally tried an IE reset: http://www.sevenforums.com/browsers-mail/163286-webserver-login-screen-missing.html#post1410311 . If you want to try it, go to Control Panel/Internet Options/Advanced/Reset.
