SYMPTOMS
When you are logged on as an administrator, you may be unable to open the Active Directory snap-ins on the domain controller. When you attempt to open Active Directory Users and Computers, the following error message occurs:

Naming information cannot be located because: no authority could be contacted for authentication. Contact your system administrator.



CAUSE
This behavior can occur when the Domain Name System (DNS) is not properly installed. Active Directory relies on DNS's being installed and functioning properly, as well as on having the SYSVOL share created.



RESOLUTION
To resolve this behavior, configure DNS properly and then attempt to open an Active Directory snap-in.



MORE INFORMATION
If the same error message appears again, perform the following procedures:


 * 1) Use the DCPROMO utility to remove Active Directory, and then restart the server.
 * 2) Use DCPROMO to reinstall Active Directory and promote the server to domain controller.
 * 3) Confirm that the SYSVOL share has been created.

After installing Active Directory, check the File Replication Service log in Event Viewer to make sure it was installed successfully.
