Question : How do I find rogue IP addresses?
I set up a Windows 2003 DHCP server, but 3 of the addresses are flagged in the DHCP server as BAD ADDRESSES. They show a unique ID in the column where MAC addresses normally show up. The IDs are e50110ac, f70110ac, and e80110ac.
One will respond to pings, the other two dont. If I delete them from the DHCP list they come back as bad addresses again.
How can I find these on the network without a lot of manually searching?
