DHCP Server service disabled by default?


  • hello,
    I install the DHCP server role without problems on Core. After this, I add the DHCP server and try build the scope with several netsh commands, but I get "access denied" error messages. From other machine I list the Services MMC, and I see, DHCP Server service state is "Disabled" by default! Why?

    I restart Core, but no changes. Certainly, after enable and start service, I configure the scope, activate and DHCP srv work fine.

  • Hi,

    The DHCP Server service is disabled by default in case you are domain joined and need to activate it in AD first.

  • OK.
    It's understandable, but it's a little bit misleading that the netsh dhcp add server _server_name x.x.x.x command is working perfect and say the server _is_ authorized - in disabled state of service.

  • Hi,

    Agreed, I'll pass this along to the DHCP team.

  • Hi,

     Did the server get authorized automatically or you did authorization explicitly?

  • Yes it is...

    At first you have to authorize the server in AD

    netsh dhcp add server FQDN_DHCP_Server_Name IP_DHCP_Server


    After that you have to change the startup configuration like this:

    sc config dhcpserver start= auto                             (mention the blank after the "start=" !!!)


    now you are able to start the dhcpserver

    net start dhcpserver


    Control your configuration with net start...


    thats it.

  •  After authorizing it in AD, and setting the service configuration to "auto" as stated above, for some reason the service will not start when I do, "net start dhcpserver". It fails with there errors,

    A system error has occured

    System error 50 has occured

    The request is not supported.

    I am logged in as Domain Admin, I even tried starting the service from the MMC -> Services on another computer, after connecting to the Server Core remotely.

    Any idea  whats missing ?
