I know what you mean about running out of hardware to run an old network -- ISA card slots, NE-2000 network cards, and 10BASE-T networks are a rare sight these days.
I have moved a number of clients running multi-user DOS applications programs successfully to Windows XP. There aren't too many situations where you cannot make a DOS program run successfully in a DOS (aka CMD) Window. Many DOS programs will still run in a CMD Windows under Windows 7 32-bit. In fact, the applications I have dealt with are far more stable under Windows XP than they were under DOS.
Depending on the requirements of your Clipper application, you may still have to contend with specific printers connected to an LPTn: port, or needing PS/2 connectors on your keyboard and mouse. There are workarounds for most of these issues without needing to touch the application.
Do yourself and your friend a favor and step up to Windows XP. You can buy a refurbished HP P4 3Ghz 1GB Ram, 80GB drive, SFF case, parallel port, PS/2 connectors, USB ports, network card, and Windows XP Professional installed for $100 to $200.
Hope this helps.

I am have trouble gathering all the information about the parts of DOS I need to start the network under Win98SE. The network is pretty simple. One server and two workstations. The program is written in Clipper.
Thanks for all help and advice.
