I've faced a strange problem in using the various web browsers. I use a Laptop with Windows 7 64 bit and I use ADSL internet connection. When I use my usual internet connection I don't have any problem, but when I use a VPN connection It is just the Google Chrome which is able to connect the internet and my other browsers i.e. Internet Explorer & Firefox could not access the internet. Also Yahoo messenger could not log in. As soon as I disconnect from VPN, the problem would wipe out. I use the Kaspersky Internet Security, But disabling this firewall & antivirus didn't made any changes.
It is worth to say that I don't have any problem with this VPN connection on my PC with Windows XP 32 bit.
Waiting for your comments.
