Again, one haws to ask, is this a 'hole' per se, or is this an 'out of
the box' setup or misconfigured setup? Big differences there eh? My
understanding is that an NT filesystem setup with anon ftp, with perms
set correctly has yet to show any holes one can drive in through. Can
you clarify this for me and others please?
Even reports about NT servers with tcp/udp port 137-139 fully exposed to
the outside have yet to show anyone being able to sidestep the services
assinged to run on those ports to put an nasty process into the box.
Has someone any info to share here that is founded in fact w/
documetation others can follow to demonstrate any real holes?

OK, so you're a Ph.D. Just don't touch anything.
