Use DHCP, then users do not have to choose an IP, it is given to them.
Plus it gives them all parameterstheyneed to configure their machineto
acces the network (like netmask, gateway, DNS...)

DHCP keeps logs of what IP wasassigne to what machine (for Windows you
have the windows name of the machine) so you can track what is what
down.

If you are dealing with users that have little knowledge and not with
hackers (and it seems to be your case) DHCPo will solve 90% of your
problems.
