An ipconfig/all should show you the address of the bad DHCP server which you can identify and take down and you will be ok.
btw what is the address range of the bad addresses? give one address.

A quick run of tcpdump -i <interface> -n port 67 or port 68 will show you all bootp traffic on your LAN. 3 -- If you did not change the scope on your DHCP server, you may end up with some wrong info. -- Mike Of course, you might discount this possibility, but remember that one in a million chances happen 99% of the time. ------------------------------------------------------------ _______________________________________________ LUG mailing list [email protected] http://kym.net/mailman/listinfo/lug %LUG is generously hosted by INFOCOM http://www.infocom.co.ug/ The above comments and data are owned by whoever posted them (including attachments if any).
