CD rom drive sharing over network

Personally ..

1 .. Install daemon Tools Lite to create a virtual DVD drive.
2 .. Create Images of DVD's
3 .. Mount the image, you can create 20+ virtual drives.
4 .. Right-Click virtual drive in explorer and use the share option, make sure permissions are given to everybody.

Doing it this way, reduces stress on dvd drive and media, won't slow up your machine as much, if lots of people asking the share.
