Event ID: 1080 occurs every three seconds when you are using Exchange Server 2003 SP2 in a clustered environment

Consider the following scenario:

• You are using Microsoft Exchange Server 2003 Service Pack 2 (SP2) in a clustered environment.
• In Exchange System Manager, you manually add a domain controller for the Configuration domain controller on the Directory Access tab of the ServerName Properties dialog box.
• After you close this dialog box, you later reopen it. You click to select the Automatically discover servers check box on the Directory Access tab. Then, you close the ServerName Properties dialog box.

In this scenario, you experience all the following symptoms:

• The following event is logged in the System log every three seconds. This event is logged even though the Exchange services are operating as expected.

• The Automatically discover servers check box on the Directory Access tab of the ServerName Properties dialog box is no longer selected. Instead, the domain controller entry that you previously specified for the Configuration domain controller appears on this tab.

This problem occurs because the Instance0 registry subkey is removed from the following subkey in the scenario that is described in the "Symptoms" section:The Instance0 subkey is removed only if no subkeys exist under the Instance0 subkey. By default, no subkeys exist under the Instance0 subkey. The Instance0 subkey is included in registry synchronization in Exchange Server 2003 SP2 clustering. Therefore, the event that is described in the "Symptoms" section is logged when this subkey is missing.
