Second solution is hard to do... no everyone my users uses DHCP.
It is not a problem sniff IP and correct MAC, and use it.

My network it's a Wireless LAN with only several computers on cable.

First solution need from me some costs. And sometimes there no 
diferrents between users.

How can I check operating system and netbios name in different way?
Are more possible differences between computers in network (with the 
same MAC and IP)?

How can I find out, that IP is being doubled?

Thanks for all replies :P
