Problems installing an Active Directory on my member server, please help

Asked By 0 points N/A Posted on -

Hey guys,

I have a Windows server 2003 O.S. with a SP2 for my machine and recently joined a network to run my computer as a server.

I have been trying to create a new domain on my network. Specifically a child domain, in the already existing network but I keep getting this warning sign;

Active Directory Domain Services Installation Wizard

The operation failed because:

  • A domain controller could not be contacted for the domain testenv.local that contained an account for this computer. Make the computer a member of a workgroup then rejoin the domain before retrying the promotion.
  • The specific domain either does not exist or could not be contacted. ”

Does anyone have an idea on how I can go ahead and bypass this problem?

you mentioned that you have connected your Win 2003 server to the network, but dear friend you need join that member server to the domain. Without joining to a domain you can't promote your computer as a child domain.

  • First of all, you need to connect your server to the existing domain.  To do that
  • Right click on My Computer
  • Go to the computer name tab and click on change button
  • Then another dialog box will appear, just click on domain option button
  • Type the name of your domain in the blank area, then you will be prompted for a user name and a password.
  • You need to have privileged user  account permissions to join your sever to the domain ( like domain admin, enterprise admin.. etc ).
  • After that you need to reboot your computer. Now you are a member of the existing domain.

You can now promote your server to become a child domain or if you have already connected to your domain,  just remove the computer from the domain.

Then do it again.

Thank you.

Basically when you want to create a child domain, you need first to create a Domain Controller in a domain and the installation of the Active Directory.  So what is really a Domain Controller?

A domain controller is a computer with AD (Active Directory) installed and is intended to be used as a server. To work with a Domain Controller you need to create it for the computer you intend to use as a server and you basically do this by installing the Active Directory.  Active Directory is a central security database that standardizes access to application data.

Steps for creating a DC (Domain Controller) are as follows:

  • Go to run and type ‘dcpromo’
  • Check the ‘Domain Controller for a new domain’ option.
  • Check the ‘Domain in new forest’ option.
  • Type the name of a new domain. Example can be ‘muchachotech.local’
  • No need to do anything on this window because the NETBIOS name is already selected by default.
  • Locate where you want to store the AD.
  • Select ‘C drive’ as your location to save the SYSVOL folder.
  • Select the second option. (By selecting this option you prompt your domain name to be reachable)
  • Input the password of your choice. Confirm your password. (Put a simple password that cannot be easily forgotten)
  • Go through your option you selected and after confirming everything is ok, click next.
  • An active Directory configuration takes place at this stage. This may take a while.
  • At this stage you will be asked to give a static IP address.
  • Select ‘Internet Protocol (TCP/IP)’ and go to properties.
  • At this stage determine the IP address of your network.
  • Click ‘Finish’ on the final stage of the Active directory Installation.

Creating a child domain of the existing domain, the above procedure except for the 3rd step of ‘Active Directory Installation Wizard’ that suggests you to create a new domain. (These are 3 options that prompt you to select which type of domain to create).
