It works. In a way. Apart from gaping security hole there's another
big problem with letters. Your script may just silently die before
reaching '/winnt/system32/net use /d m:' line. In that case (at least
on NT 4.0) you'll be left with exiting, but unaccessible, undeletable
and unchangeable 'm:'. Next time your script won't be able to run at
all. You'll need to restart your machine to get rid of it

So, i strongly suggest using UNC everywhere where possible.
