The information in this article applies to:

- Microsoft Windows NT Server version 4.0 
- Microsoft Windows NT Server, Enterprise Edition version 4.0 
- Microsoft Windows NT Load Balancing Service 1.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Your Windows NT 4.0 Server-based computer may stop responding (hang), or you may
receive the following error message in Wlbs.sys:

  STOP: 0x0000000A (0x00000001 0x00000002 0x00000001 0xeb597fc0)

Note that the parameters for the "Stop" error message may vary.

CAUSE
=====

This behavior occurs because the Windows Load Balancing Service (WLBS)
connection queue becomes corrupted when it sees packets with a source IP address
of 0.0.0.0.
