I have about 140 PC's on a network and I am running the WIN 2k DHCP
server. I am constantly have problem from PC's getting into IP
conflicts. None of the names or physical addresses are the same, it's
like it is not communicating the DHCP server correctly? I have heard
their is a registry fix for this? Anyone know anything about this?
 
You should enable conflict detect which will prevent the DHCP server from giving out addresses that are already in use. You
should then investigate the source of the IP conflicts. The server will not give out an address that it already has as leased in it's
database. This is typically caused by a rouge DHCP server on your network.

To enable conflict detection, open the DHCP MMC. Right click on the DHCP server and choose properties. Click on the
Advanced tab and set the "Conflict detection attmpts" value to 3.

To find out if there is a rouge DHCP server, setup a packet sniffer on your network at various locations and see if multiple DHCP
servers respond to client DHCP requests.

Thank you,
