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.
