Hello,

Strange leases started to appear on my DHCP server (W2K
DC). The name of PC consists of letters and digits and it
has different domain than DHCP server is in. DHCP log
shows strange MAC address which is more that 20 symbols.
I'd like to "sniff" all attempts to get the leases from
DHCP server. Which ports and protocols use DHCP server? Or
may be you know other way to resolve this issue?

Thank you in advance,
Oleg

Is there a Wireless Access Point or bridge on the network ? If so, I'd
start looking there first.
