After you install Active Directory, you may be unable to start the Active Directory snap-ins on the domain controller. When you try to start the Active Directory Users and Computers snap-in, the following error message may appear:
Naming information cannot be located because: no authority could be contacted for authentication. Contact your system administrator.
This behavior can occur when Domain Name Service (DNS) is not correctly configured.
To resolve this behavior, make sure that the zones on your DNS server are configured correctly and that your DNS server is authoritative for the zone that contains the Active Directory domain name.

Try again to start the Active Directory Users and Computers snap-in. If you receive the same error message, use the DCPROMO utility to remove Active Directory, restart your computer, and then use DCPROMO to reinstall Active Directory. Verify that Active Directory has been installed successfully.
Before you install Active Directory, you must install and configure a DNS server that is authoritative for your Active Directory domain name. Active Directory depends on DNS to function correctly and requires the creation of the SYSVOL share.

NOTE: The SYSVOL share must be installed on an NTFS partition. At least one NTFS partition must be present on your domain controller in order to install Active Directory.

To verify that Active Directory has been installed successfully:
  1. Start DNS Manager, and then verify that the correct DNS entries have been created, by comparing the entries in DNS Manager with the entries in the Netlogon.dns file, which is located in the %SystemRoot%\System32\Config directory.
  2. Verify that the SYSVOL share has been created, and that it contains the NETLOGON share and the Policy and Script folders.
  3. Start the Active Directory Users and Computers snap-in, and make sure that your domain controller appears in the Domain Controllers container for the domain you specified.
  4. Open Event Viewer, and then review the entries in the File Replication Service Log, the DNS Server Log, and the System Log to make sure that Active Directory has been successfully installed.
