It is not a supported OS version for FileMaker Server.
However, I and some others have reported success on this type of server. YMMV.
Thank you David.... I am hoping it doesn't cause me any problems, especially as I do not need the web interface side of it at all (will be a while until I go down that route).
Was it quite straight forward to get working, or did you have to do lots of little tricks and things to get success?
It was a standard install that worked for me. Fingers crossed.
