JSI Tip 8172. When you establish a VPN connection, you receive a 0x000000D1 BSOD?

When you establish a VPN connection, your computer Blue Screens with:

STOP: 0x000000D1 (0x00000020, 0x00000002, 0x00000000, 0xf5bf0f68)

This problem will occur if Windows NT 5.x (Windows 2000, Windows XP, or Windows Server 2003) is your operating system, you have a NIC from the Intel PRO/100 S adapter family, IPSec offload is turn on, and IP checksum offloading is turned on.

NOTE: See http://support.intel.com/support/network/adapter/pro100/sb/cs-009908-prd59.htm.

To workaround this behavior, use the Intel PROSet program to turn off turn off IP checksum offloading. You could turn off IPSec offloading, but turning off IP checksum offloading would be better.

You can also configure these settings using the Properties of appropriate Network and Dial-up Connection, pressing Configure on the General tab, and selecting the Advanced tab.
