IM driver -ndistester 3.91 - Unable to determine media type

Hi All,

I am testing my NDIS IM driver with ndistester 3.91 on Windows 2000 Server.
But it can not detect my virtual miniports created by my IM driver so I am unable to
run any of the test.

When connected with debugger it says …

0:++NDTEST++ Unable to determine media type.
0:++NDTEST++ Device not added.

From kd I have verified that !ndis.miniport xxx(my virtual miniport) give me correct
information (that it is a 802.3 media). I have also verified that MEDIA_TYPE OID returns
correct value. I can also install my IM driver create virtual miniports and send/rev
packets over the ethernet.

Any inputs would be helpful.

Thanks in advance.
Ram

P.S. The MS MUX driver’s virtual miniport can be seen in ndistester 3.91. My IM driver is based in MS MUX sample!
