Domain controller requirements
For the Active Directory domain controller, you should verify that you have access to a computer with a supported version of the Windows Server product family and is configured with the domain controller and DNS server roles. For details about supported platforms, please consult the release notes.
In addition, you should verify that the domain functional level is at least Windows Server 2008 R2.
To determine the domain functional level:
- Open Active Directory Users and Computers (dsa.msc).
- Select the domain.
Select Action, then click Raise domain functional level.
If the current domain functional level is not at least Window Server 2008 R2, use the drop down list to raise the level.
