Operating System

Windows Server 2008 R2, Windows Server 2012


Dynamic Host Configuration Protocol (DHCP)





The DHCP server does not have full control permissions to the DHCP registry parameters.

The DHCP server will not be able to read or write to its registry configuration and will not start.

Assign the DHCPServer service full control permissions to the DHCP registry.

  1. Click Start, type regedit in Start Search, click Yes in User Account Control if prompted, and then press ENTER.

  2. In the registry tree, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Services\DHCPServer.

  3. Right-click DHCPServer and then click Permissions.

  4. In Group or User names click DHCPServer if a DHCP Server is already present. Otherwise, click Add in Select Users or Groups.

  5. Click Locations and select the hostname of the system, enter NT Service\DHCPServer, and then, click OK.

  6. In Permissions for DHCP Server check Allow for Full control and then click OK.

For updated detailed IT pro information about DHCP and selectively enabling or disabling DHCP server bindings, see the Windows Server 2008 R2 documentation on the Microsoft TechNet Web site.
