Cannot connect to any Microsoft website and Log in to some bank websites

Hi,



Hi,
I just got my laptop reformatted and Vista installed again.
I can access all websites like google and this one but i cannot connect to any
1. Microsoft website or MSN website or log into the MSN messenger.
2. When i log into HSBC Hongkong page, it does not log in. (Surprisingly i can log on to the HSBC India website)
My windows update is working fine and has been able to download and install updates including Service Pack 1.
I would be greatful for any help. This is the second computer i am facing this problem with. I also have another laptop which has excatly the same problem after upgrading to Vista.
The date and time zone is correct and have changed the region from US to Hong Kong.
I have run Spybot and Symantec Scans and the system came clean.

I have been searching for a solution on google for 2 days and tried most things recommended like cleaning DNS cache.

When i ping the DNS 4.2.2.1, i do get a response.
