You receive a stop error after you enable the RequireinClearout mode on an IPv6 network on Windows Server 2008 R2 or in Windows 7

Not sure if this is the right fix? We've added this issue to our memory dump diagnostic which can confirm.
Symptoms
Consider the following scenario:

  • A computer is running Windows Server 2008 R2 or Windows 7.
  • The IPSec tunnel is configured on a network by using IPv6 transition technologies, such as Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) or IPv6 over IPv4 (6to4).
  • The RequireinClearout mode is enabled on the IPSec tunnel.

    Note This option is only valid on computers that are running Windows 7 or Windows Server 2008 R2.
In this scenario, the computer restarts unexpectedly and you receive the following error message:

0x000000D1 (parameter1, parameter2, parameter3, parameter4)
DRIVER_IRQL_NOT_LESS_OR_EQUAL


Notes
  • The four parameters in this error message vary. This depends on the configuration of the computer.
  • Not all " 0x000000D1" Stop error codes are caused by this problem.
Cause
When an outgoing clear text packet is sent by using the IPSec tunnel, an access violation occurs. This behavior triggers the error message that is mentioned in the "Symptoms" section.
