DHCP Server Locator Utility displays the DHCP servers active on the subnet. If it detects any unauthorized DHCP servers, it beeps and sends out alert messages. It also displays packets that it detects from DHCP servers; you can specify whether to display packets from all DHCP servers or only from unauthorized servers.
You can use this command line-based tool to determine which DHCP servers are available to a DHCP client and to detect unauthorized DHCP servers on a subnet.
Important
DHCP Server Locator Utility should not be run from a DHCP server. The tool listens for DHCP servers by taking DHCP packets off the IP stack. However, it has no means to reintroduce DHCP packets to the stack. Therefore, running this tool on a DHCP server will preempt DHCP requests and the DHCP server will appear not to respond.
