DHCP Conflict between a Cisco Router and Windows DHCP Server

In a response to my post Redundant DHCP Server I've speculated that a Cisco router should coexist with a Windows-based DHCP server if you configure them with non-overlapping address ranges. I was wrong, Edgar Cahuana discovered that Microsoft's DHCP server wants to have complete control over the LAN it's serving and shuts down if it detects another DHCP server on the same LAN.

To make the two DHCP servers coexist, you have to disable rogue DHCP server detection in Windows DHCP server.

    Fixed. Thanks. You've also enhanced my language skills; I had no idea a french color is also a valid english word :)) ... which is why the spell-checker did not complain.

    I believe this is only true for SBS. Non SBS versions can co-exist with other DHCP servers - David
