How do I access a Mapped Drive in DOS???

I have installed Win Xp from my hard drive many times and find that this works faster than install from CD. I utilize two Hard drives with the a copy of WIN XP on the slave drive and just boot to a DOS prompt and access the folder I386 containing WINNT.EXE and run the XP setup from there; works just fine.

I am intrigued at the idea of mapping a drive to the I386 folder on my slave and installing XP from there BUT I am not sure how to access the mapped drive (Z) from DOS (I386 folder); I thought it would be like accessing any "real" drive but not so.

Somebody tell me what I'm missing please.

I want to be able to just do the following:

A:>Z:
Z:WINNT.EXE [enter]


Somebody tell me what I'm missing please. Do I need a different type boot disk? What?

:confused:

The DOS command is:

net use Z: \\server\share

Note the space between Z: and \\......
