Well, I only really need them to be able to access a single application across the network which runs from this single workstation. The application is designed to be run for "unlimited users" from a single centralized computer which has all the data on it.
In retrospect, I should've just bought server to begin with, (I put a SCSI hard drive in it!) but I was hesitant to believe that its use would catch on...
Any ideas would be appreciated!
