Hi and welcome to Korg!
Just for starters - no need to shell and use 'net use', just use 'use' (damn, abuse of use ^^; ).
Second, what is the reason for doing this they way you have chosen?
Third, the command-reference (at the 'start' of www.kixtart.org) and the FAQ here in the forums is your friend.

Sorry for a short answer, having my own kix-issues right now =), hope you'll get some help from the regulars/gurus =)
