When the SPX protocol is used with a network adapter driver that is NDIS 4.0 compliant, a STOP 0xA error message may be displayed in Ndis.sys.
This problem occurs because the Nwlnkspx.sys driver allocates its own NDIS packets. It does not call the NDIS library routines that allocate NDIS packets for protocol drivers. Because Nwlnkspx.sys allocates its own packets, it does not initialize reserved fields in the NDIS packet structure used primarily by NDIS 4.0-compliant adapter drivers.
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to:
