In the "General Hardware Considerations For FileMaker Server" the first suggestion is: "Use a dedicated machine / system for FileMaker Server: FileMaker Server should be installed and run on a dedicated machine whose sole purpose is to be used as a database server. There are many reasons why you should consider dedicating a system to FileMaker Server."
The paper gives lots of good information on server requirements, but it doesn't say what these many reasons are for using a dedicated machine. Performance and stability seem obvious, but if the database has only a few users, is it really necessary?
Thanks for your idea,
