Stop 0x0000000A in Tcpip.sys Caused by Invalid Fragment Bit (164409)

SYMPTOMS

A computer running Windows NT may display one of the following blue screen STOP error messages while it processes a datagram packet:

STOP 0x0000000A IRQL_NOT_LESS_OR_EQUAL

-or-

STOP 0x00000019 BAD_POOL_HEADER

CAUSE

A router incorrectly set the packet fragmentation bit on a browser broadcast datagram packet. The Tcpip.sys driver attempts to reassemble this packet and causes pool memory corruption.

RESOLUTION

To resolve this problem, obtain the fix mentioned below. The new Tcpip.sys driver will now check the length field on the packet to prevent it from processing fragments that do not exist.
