While we're on the issue of creating known devices under Windows.  An
issue I remember noting awhile back is that under Windows NT, it's
possible to create and remove most of these devices over a file
share.  They aren't treated as special files.  You cannot however
create or remove these files locally.  I imagine that this is due to
the fact that there are descrepencies between file operations
processed through the CIFS layer, and operations processed locally.
While this probably isn't a serious issue, the main problem is that
someone could create a large number of these files (as I recall you
could use a large number of variations), and the local user would not
be able to remove them, since they can only be removed via a network
share.  More an annoyance than anything..

I'm too lazy to look it up this morning, but there is a knowledge base
article on this - you can get rid of them locally, you just use a port of
rm that runs in the POSIX subsystem - these are DOS devices, and the POSIX
subsystem knows nothing about them.  So rm ./con works nicely 8-)

BTW, a POSIX version of rm comes in the resource kit.
