Hi,

Anyone care to comment on these server operating systems? I'll start:

In my opinion, FreeBSD is the most stable, Windows Server is the most user friendly and Red Hat is in the middle - a combination of the stability of FreeBSD with the friendly GUI of Windows (with X Window).

Windows and Red Hat supports more hardware types than FreeBSD, however FreeBSD works well (much better than Red Hat or Windows) under heavy traffic. If you have ever realised, most large sites run FreeBSD or other kinds of BSD - Sites with 1TB+ downloads everyday. Microsoft's Hotmail once ran on BSD (This was before the site remake about two years ago).

But the most stable OS I know of is probably BSD/OS. BSD/OS is known for running for years without crashing or needing a reboot.
