SYMPTOMS
========
A Stop 0x0000000A occurs in Tcpip.sys when receiving Out of Band (OOB)
data.
CAUSE
=====
A sender specifies "Out of Band" data by setting the URGENT bit flag in the
TCP header. The receiver uses the URGENT POINTER to determine where in the
segment the urgent data ends. Windows NT bugchecks when the URGENT POINTER
points to the end of the frame and no normal data follows. Windows NT
expects normal data to follow.
RESOLUTION
==========
Microsoft has updated Tcpip.sys to correct the problem. Instructions for
installing it are available from Microsoft support channels, or directly
from the following Internet locations:
