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.
