I resolved with 10.10.10.1! I've not realized that I need connect with the network cable an active PC to enable the IP defined in Network Preference.
I don't remember if OSX10.0.4 worked in this way. There is a way to disable this automatic feature and make always enabled my Network Preference IP? Because in this way i can't leave active the server on the Mac when other PC are down, I need to restart the server on the Mac after at least a pc makes active.
