There are some problems with Dos as a network layer
First of it doesnt nativly support network. This means you will have to hunt down the necessary files.
To run a network on ipx you will need the following ( i may forget some its been a while)
ie ne2000.com/3c509.com (network driver for dos)
ipx.? (com/exe) or ipxodi. ? (com/exe)
This will enable the network (transportation layer)
However there is no network sharing of any kind in this, this will only enable communications on the ipx protocol
To utilise the transport layer you will need a "file" interface or network system.
i can recommend the following two
Nowell network light (include lsl, ipx etc)
FX (Fast lynx)
I dont say these two are the best they are the ones i am able to remeber
