  • DHCP Manager for Windows 2008

    environment:

    Two separate active directories, PROD and DEV.
    There is currently not a trust relationship between the two as we build our new DEV environment.

    domain controllers:

    dc01.dev Windows 2008 R2 ( DNS and DHCP)
    dc02.dev Windows 2008 R2 (DNS )

    dc01.prod Windows 2003
    dc02.prod Windows 2003
    dc03.prod Windows 2008 (DNS and DHCP)
    dc04.prod Windows 2008 (DNS)

    my workstation:

    desktop.prod Windows 7


    I need to access DHCP manager on dc01.dev

    Usually, I do this via a Remote Desktop session to dc01.dev. However, two people are currently logged in, which is the limit.

    I see two options:

    1. Install DHCP administration tools on dc02.dev , which I have done, and it works fine.

    2. Use the DHCP Manager on my Windows 7 desktop in the PROD environment to manage DHCP in the DEV environment.

    Without a trust relationship between the two environments, is there a way to manage DHCP in DEV from my PROD workstation?

    Re: DHCP Manager for Windows 2008

    if you can ping the dev domain, you MIGHT be able to start the dhcp mgr on your workstation using explicit credentials for the other network, even without a trust.

    similar concept to taking a computer from one domain (say a laptop) onto another domain, and mapping a network drive passing explicit credentials

      Hi,

      Use the DHCP Manager on my Windows 7 desktop in the PROD environment to manage DHCP in the DEV environment.

      You won't be able to do it. You need to have trust relationship in order for it to work. Otherwise RDP. if you go ahead and add Server to dhcp console it will not ask for creds [i have tried with ip] and show you red - on the server
      Thanks & Regards

          from my PROD workstation:

          Microsoft Windows [Version 6.1.7600]
          Copyright (c) 2009 Microsoft Corporation. All rights reserved.

          C:\>runas /user:dev\robertr mmc

          Enter the password for dev\robertr:

          Attempting to start mmc as user "dev\robertr" ...

          RUNAS ERROR: Unable to run - mmc
          1787: The security database on the server does not have a computer account for this workstation trust relationship.

          C:\>


          The result is the same whether I use \dev or \dev.company.tld

            Re: DHCP Manager for Windows 2008

            Some quick searching of the error message found this suggestion to add the /netonly switch

            runas /netonly /user:dev\robertr mmc

            which opens up the mc without any error messages.

            But why I try to manage the DEV DHCP server, I get the server icon with a red circle, and the "There are no items to show in this view" message in the view pane.

              Hi TechCamel,

              Run as won't work because it won't be able to authenticate because there will be no domanPro\userA. Runas would work when you have a user on same domain/local computer with necessary privilege however you are logged on with different creds for security reasons but now need to run a service/app which require higher privilege

              Hope this sheds some light. and thank you for asking question
