I had this problem once, here is how we resolved the problem run Winipcfg and find the Servers IP address Ping the address from a machine plugged into your backbone start unplugging segments from your network, when ping fails the you have narrowed it down to a segment... now if you cannot ping (if it is an invalid IP for example) keep requesting IPaddresses while you unplug segments... I think this may be the brute force way of doing things, but it works... -munir >>> Amy Tanner <amy at real-time.com> 09/12/01 10:21 AM >>> Any tips for finding a rogue DHCP server, that is a device answering DCHP requests? I'm having a problem where some device must be answering DHCP requests and offering 192.168.1.X addresses, that shouldn't be.
