How can I stop/start all Mac OS X Server services at once? When doing maintenance on our OS X Server (10.8.4), I need to shut down all server services one by one. While it is not too much of a drag to click all services off, perform maintenance, and back on, I wonder, if there is a way to automate this procedure. 

Is there?
You could do it from the command line and/or write a script with the relevant services:

sudo launchctl list


And for ssh (remote login) for example

sudo launchctl stop com.openssh.sshd


Bringing them back up then with start (instead of stop)
