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. David LeBlanc dleblanc () mindspring com
