You lose Internet connectivity after you install Windows Vista Beta 2 on a computer that is behind a home router or gateway

Symptom
After you install Windows Vista Beta 2 on a computer that is connected to certain home routers or gateways, you may lose Internet connectivity. You may be able to ping Internet sites from the computer, but you cannot browse any Web sites or communicate across the home network to any other computers by using TCP/IP.

Note
Connectivity to resources that are located behind the same router or gateway is not affected. Also, this issue does not affect connectivity from other computers that are behind the same router or gateway. This issue affects wireless and wired hosts in the same manner.

Cause
This issue occurs because the router or gateway does not support Windows Scaling. By default, Windows Scaling is a new feature in Windows Vista Beta 2 that is enabled. This feature is Internet standards based (RFC 1323). If the router or gateway does not support this feature correctly, the router of gateway may drop packets that use this feature. Because of these dropped packets, the TCP connection cannot be established. TCP is used by most network-based applications. Therefore, Internet connectivity is lost.
