MS TCP/IP Does Not Load with ODINSUP on Token Ring (108660)






This article was previously published under Q108660

SYMPTOMS

On a LAN Manager 2.2 enhanced MS-DOS workstation under Windows for Workgroups 3.1 or 3.11, trying to load Microsoft TCP/IP on top of a Novell Netware ODI MLID and ODINSUP fails with this error:
Unloadable TCP 1.0 not loaded
Microsoft NetBEUI loads and functions in this configuration.

CAUSE

TCP/IP issues an OpenAdapter NDIS call to determine if a token ring network card is available and functional. If this call fails, TCP/IP fails to load.

Novell's ODINSUP NDIS support layer for ODI drivers does not provide support for the OpenAdapter call. Instead it performs its own adapter initialization and sets bit 4 of the MAC status table's flag field to indicate that the adapter is already open.

RESOLUTION

The TCPTSR driver was changed so that it does not attempt an OpenAdapter NDIS call until it checks bit 4 of the MAC Service Specific Status Table to see if the adapter is already open. This fix is available as CSD00.071.
