Active Directory Connector server is not executing any connection agreements and is a candidate for removal

[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime. For more information about the tool or to download the latest versions, see "Microsoft Exchange Analyzers" at http://go.microsoft.com/fwlink/?linkid=34707.]

The Microsoft® Exchange Server Analyzer Tool queries the Active Directory® directory service to determine the value for the msExchChildSyncAgreements attribute, which represents the connection agreements that are executing on an Active Directory Connector (ADC) server. This attribute is a multi-valued string and is set on the following Active Directory object: CN=Active Directory Connector (ServerName),CN=Exchange Settings,CN=ServerName,CN=Servers,CN=SiteName,CN=Sites,CN=Configuration,DC=Domain,DC=com

The Exchange Server Analyzer retrieves the number of entries (count) in this attribute. If the count is 0, it indicates that no connection agreements are running, and a warning is displayed.

If it is determined that all the required connection agreements are being executed on other ADC servers, the ADC service on this server should be removed or disabled. Running the ADC service without any connection agreements does not cause problems. However, it is recommended as a best practice to not run services if they are not required. Therefore, you should either disable the ADC service or uninstall the ADC service from this ADC server.

  1. To disable the ADC service on the server running the ADC service, right-click My Computer on the desktop, and then click Manage.

  2. Expand the Services and Applications node, and then click the Services node.

  3. In the right pane, right-click Microsoft Active Directory Connector and click Properties.

  4. Change the Startup Type to Disabled. The next time the computer starts, the ADC service will not start.

  5. Click Apply, and then click OK.

If you decide to uninstall the ADC service, you can use the Microsoft Exchange 2000 Server or Exchange Server 2003 CD to do so. Go to the \ADC\I386 folder and double-click the Setup.exe program. Follow the prompts to uninstall the ADC service.
