Installing SharePoint Server 2010 on Windows Server 2008 R2 and SQL Server 2008 R2 - Part 4: Active Directory installation and configuration

This guide shows you how to install and configure Windows Server 2008 Active Directory Domain Services. This isn’t necessary but if you are going to deploy a development environment I suggest to create a closed environment.

This way you have everything on your own so you don’t depend on something or someone.

Development Environment:

This step usually applies to developers creating an isolated dev environment independent of your companies infrastructure. You are independent, can go where you want without a connection to your company and you can make changes as you want.

Active Directory installation

Don’t use the server manager to install the Active Directory role because you are prompted to use dcpromo.exe and you are left with an uncompleted installation.

Don’t use the server manager to install the Active Directory role . Using server manager  you are left with an uncompleted installation.

Open the ”Run” dialog box and type dcpromo.

 Open the run dialog box and execute dcpromo. The Active Directory installation wizard is starting up.

Click next checking ”Use advanced mode installation”.
Click next and after that check ”Create a new domain in a new forest”.

Use the advanced installation mode. Check Create a new domain in a new forest.

Type a new full qualified domain name like “aglaser.net”.

Type a NetBIOS name like “AGLASER”

Type a full qualified domain name. Type a NetBIOS name.

Select a forest functional level and select a domain functional level.

Note: Please be aware that your choice affects other things. Here is a comment from Wes Preston which you should consider if you are installing a all-in-one demo machine:

- If selecting AD-2003 mode, the SPAdmin account needs to be added to the Domain Admins group in AD
- If selecting AD-2008 R2 mode, the SPAdmin account can be added to the Local Admins group

Please test it by yourself.

Set the forest functional level. Set the domain functional level.

Make sure “DNS server is checked.
After clicking next you may get a warning that one of your network adapters has a dynamically assigned IP address. Click “Yes if you are sure you have one network adapter with a static IP address.

Check DNS server to install a DNS server. Click Yes if you have one network adapter with a static IP address.

Click “Yes” because you don't have to care about a DNS server in a parent zone since this is a testing environment.
Click next again.

Click Yes because you dont have to care about a DNS server in a parent zone since this is a testing environment. Click next again.

Type in a “Directory Services Restore Mode Administrator Password”.
Click next to start the installation wizard.

Enter a Directory Services Restore Mode Administrator Password. Start the installation process.

After installing the AD and the DNS server you have to restart your computer.

The Active Directory installation has finished. After the Active Directory installation has finished restart the server.

Active Directory configuration

So far I didn’t need to do any configuration since the out-of-the-box installation was enough. If you see the following screens you are fine.

Active Directory installed roles. Active Directory installed features.
