We are running (2) PCs with network versions of ACAD 2002, LDT, CAD Overlay and 3D Studio VIZ. Seems so long ago that I did the network installation, I now have the 2004 CD in front of me...and am at a loss on where to begin. We are running a windows 2000 server. This is the first network upgrade for me (as we always ran stand alones)...Do I have to start from scratch again? Thanks for any help... -Mike
