And how are you going to share it from that machine?
From a shared volume? That's a really bad idea
From FileMaker Pro? better, but not great
From FileMaker Server? Best option, but research the system requirements before attempting to purchase and install.
It's highly recommended to NOT run filemaker server on a server that is performing other functions, such as user directories, DHCP hosting and file sharing.
The issues you'll into is the system fighting for resources which would result in a performance loss, as well as potential security considerations, and functions for filemaker conflicting with ports used for other services (EG port 80). DIsk space will also become a consideration. Not sure what hardware you are attempting to run.
