Tony, on your machine with the CD-rom you can share the CD drive, simply right click on it, click sharing and enable it.

As for mapping the CD, in your network neighbourhood (on the tablet) click on the shared drive, then in the top menu bar click on "map network drive".

HOWEVER; some applications will refise to install like this, they "demand" a CD drive to be physically present in the PC, in that case you'll need some kind of virtual CD drive application.
