using SPAWN to work with Windows NT network directories

[differentiable(at)hotmail.com (Lucas Miller)]

i'm trying to use spawn to create a directory on our Windows network
server.
i can do this locally with the following commands:
 
 IDL> cd, 'c:\temp'
 IDL> spawn, 'md mydirname'

will make a directory 'c:\temp\mydirname'.  When I try this across the
network
however, eg.,

 IDL> cd, '\\Devsrvr\Users\me\'
 IDL> spawn, 'md mydirname'

i don't get anything.  I can use cd in combination with findfile()
across the network, but i can't get spawn to do anything for me on
devsrvr.  Any ideas?
Thanks!  Lucas
