Trick parallels into believing it has a network drive?

I have an interesting situation I've searched some on, but would like some advice as to the best route to take...

I run autocad in my winXP VM. Autocad uses certain windows directory paths for support files and what not. I now have a 'client' that runs their cad system as workstations from a server. In order to have my cad files compatible wit theirs, all of my directory reference & paths must match theirs, which all point to their server. N:\

I need to figure out how to create a virtual disk/drive and way to configure parallels to see it as a network drive, (even though it won't be residing on a network). Anybody got any ideas on how I should go about doing this? Thanks.
