NDISWANIP key lost in XP Professional

Running XP pro with the latest patches. At boot time I
get this message (event ID 4191) in the system event log:

"IP could not open the registry key for adapter
TCPIP\Parameters\Adapters\NDISWANIP. Interfaces on this
adapter will not be initialized."

When I update tcpip configuration on the local
connection, the changes take effect but are not visible
the next time I open the propertes window.

MSDN library has a workround for this for Windows 2000,
but this will not work in XP.

Any suggestions?

Thanks
