Is there a way I can let MS know about possible bug/problem I see while running ndistest6.5?

Hi,

While running ndistest 6.5 sometimes, stats test-case throws a window
cribbing something about xml…
If I would like to bring it to notice of MS and check with them whether
this is a tool issue to basically
narrow down a problem (either with driver/test tool), is there a channel to
do so?
For eg. like DDK feedback?

Thanks,
