DHCP Dependent Service Health Monitor

Microsoft.Windows.DHCPServer.Library.Server.UnitMonitor.DependentServiceHealth (UnitMonitor)

Knowledge Base article:

Summary

The Dynamic Host Configuration Protocol (DHCP) Server service is dependent on these services:

Service Controller
Global parameters initialization
Registry parameters initialization
RPC server start
Winsock data initialization

The failure of any of these services to initialize or start can cause the DHCP Server service to fail.

Resolutions

Restart dependent services

To verify that the DHCP Server service is running:

At the DHCP server computer, click Start, click Run, type cmd, and then press ENTER.
At the command prompt, type sc queryex dhcpserver.
If all dependent services have started successfully, the DHCP Server service should be shown as RUNNING.
