Hi All.
Happy Thanksgiving!
I am working on an NDIS IM for XP.
Everything's fine until I found that with certain NIC
cards the XP system crashes when I issue "telnet 152...."
in a cmd box.
I am scratching my head because with other NIC cards I can
run the same command without any problems.
When I traced the problem the IM caused the BSOD(0xd1)
when it tried to free a buffer.
What is so special about the telnet command?
But I still can't figure out why.
Any ideas?

0xD1 is very common in early stage of the driver development. Without
further info, it's hard to tell the root reason. Can you post the output of
!analyze -v here?

I would suggest you run NDIStester with Driver Verifier enabled on your IM
if you haven't done so. As Stephan (a NDIS guru in this NG) said, we should
run NdisTester as soon as the driver can be installed.

Good luck,
Calvin

Thanks Calvin.
Where do I get the NdisTester?

Also take a look at the great article about NDIS test:
