DCPROMO on Windows Server 2008

Jul

 « »    

From my Windows Server 2008 machine, I will be running DCPROMO to turn it into a domain controller for my new domain.

Prerequisites

Networking

Before we run DCPROMO, we need to make sure we have a Static IP Address set. If this is your first Domain Controller on your network set the DNS server to the same IP address you set for the server itself. This is because we will be installing DNS with this Domain Controller. For clients in an Active Directory domain they must point to a DNS server located on a Domain Controller.

If you are connecting to an existing AD domain then point the Preferred DNS server to another AD Domain Controller. After AD is installed you can point the Preferred DNS server to itself and point the Alternate DNS server to another AD Domain Controller.

Password

If this is a new AD installation, change the administrator password to a complex password or you will get this error during installation

DCPROMO

Press the Start button then enter “DCPROMO” and press “ENTER”

Press “Continue”

The setup will detect if the binaries are installed and if they are not it will install them

Using Advanced Mode Installation

The improvements to the Active Directory Domain Services Installation Wizard are all available by default. However, some wizard pages appear only if you select the Use advanced mode installation check box on the Welcome to the Active Directory Domain Services Installation Wizard page of the wizard.

Advanced mode installation provides experienced users with more control over the installation process, without confusing newer users with configuration options that may not be familiar. For users who do not select the Use advanced mode installation check box, the wizard uses default options that apply to most configurations.

The new option on the Welcome page of the wizard enables advanced mode installation as an alternative to running dcpromo at a command prompt with the /adv switch (dcpromo /adv).

The following table lists the additional wizard pages that appear for each deployment configuration when you select the Use advanced mode installation check box.

New forest Domain NetBIOS name
New domain in an existing forest On the Choose a Deployment Configuration page, the option to create a new domain tree appears only in advanced mode installation.

Source Domain Controller

Check “Use advanced mode installation”

Press “Next”

Microsoft’s message letting you know NT 4.0 clients might have issues with Windows Server 2008 Domain Controllers

Press “Next”

We will be creating a nee domain in a new forest.

Select “Create a new domain in new forest”

Press “Next”

Enter the name of the new forest root.

Press “Next”

At this point it will check to see if the forest name is in use, since we set the DNS server to itself – it will not get very far.

Enter the NetBIOS name of the domain. This is for clients who use NetBIOS, you want to keep this under 8 charaters for true NetBIOS clients. I don’t have any of those so my domain is 9 charaters

Press “Next”

Domain and Forest Functional Levels

2008: This forest functional level does not provide any new features over the Windows 2003 forest functional level. However, it ensures that any new domains created in this forest will automatically operate at the Windows Server 2008 domain functional level, which does provide unique features.

2003:
The Windows Server 2003 forest functional level provides all features that are available in Windows 2000 forest functional level, and the following additional features:

–    Linked-value replication, which improves the replication of

changes to group memberships.

–    More efficient generation of complex replication topologies

by the KCC.

–    Forest trust, which allows organizations to easily share

internal resources across multiple forests.

Any new domains that are created in this forest will automatically operate at the Windows Server 2003 domain functional level.

2000:
The Windows 2000 forest functional level provides all Active Directory Domain Services features that are available in Windows 2000 Server. If you have domain controllers running later versions of Windows Server, some advanced features will not be available on those domain controllers while this forest is at the Windows 2000 functional level.

Choose “Windows Server 2008”

Press “Next”

Setup will check our DNS configuration

Select “DNS sever” to make this server a DNS Server

Press “Next”

Press “Yes”

You can change these locations but why would you. If you are running low on space on your C drive then why even make the box a domain controller?

Press “Next”

Enter a password for the “Directory Services Restore Mode Administrator”

Confirm the password

Press “Next”

Press “Next”

Active Directory will install

Press “Finish”

Press “Restart”

After the reboot you should have several Active Directory related tools under “Administrative Tools”
