I wouldn't know the right order, and even if you did stop and start 
everything in the right order, it may not fix the problem.  Your problem 
could be in the network stack, or someplace else.  That is why I usually:
"If in doubt, reboot it out"

Your users already couldn't connect correctly, so no real harm in a reboot.
