I'm going to be setting up a network for a small office soon. The network will consist of about 5 workstations (soon to be more) and 2-3 servers (one "real" server and a couple workstations-turned-servers to take some load off the main machine).
I've been asking around to see what server Linux distros people prefer, and it seems like everyone is biased towards using traditional RedHat-like server distros. Every time I mention running an Ubuntu server, everyone says I should run Red Hat instead, but I have yet to hear any reasons not to run Ubuntu servers.
I'm more familiar with using Ubuntu/Debian servers, are there any significant reasons why I should run another server distro that outweigh being familiar with an OS?
