SYMPTOMS
When you are using the Active Directory administration tools, you may receive the following error message:

The server is not operational

This message may be displayed when you open a Microsoft Management Console (MMC) snap-in, or while you are using a snap-in after a domain controller has been located.



CAUSE
This error message may be caused by any of the following situations:
 * The network configuration of the client is incorrect. This includes the absence of addresses or incorrect addresses for DNS servers to locate and resolve domain controllers.
 * The configuration of the Winsock Proxy client is incorrect, preventing the correct resolution of available domain controllers and their addresses.
 * Network connectivity between the client and the domain controllers discovered by querying DNS is not available.
 * Communication over the network to the domain controller is functioning properly, but an invalid response was returned to the client.
 * The domain controller used as the data source while the MMC snap-in is open has become unavailable.



STATUS
This behavior is by design.
