I have been trying to track down the owner of a unknown IP address for about a week now and its driving me crazy cause I cant find it. The ip address is excluded from Windows 2003 DHCP distrubution. I have verified all static IPs of printers, and servers - I have done a port scan and all ports are closed, I have tried to run psexec cmd to see if I could get into cmd, I have tried to open the ip in a web browser, I have tried to run a packet capture on the ip (no packets seem to be sent of received). Is there any other way I can figure out what this IP belongs too?
BTW I do know what the MAC address is
