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 Lenthir _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
