SiteName is hard-coded

[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 reads the following registry entry to determine if the SiteName registry value is present on the Exchange server:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Netlogon\Parameters\SiteName

If the Exchange Server Analyzer finds the SiteName registry value present, a warning is displayed.

This warning indicates that the Active Directory® directory service site membership has been hard-coded on this computer running the Microsoft Windows® operating system. This configuration is not recommended for Exchange Server.

When you hard-code a Windows site, you can cause failures of the Microsoft Exchange System Attendant service and general Exchange Server failures. You should consider removing the SiteName registry value. If you remove the SiteName registry value, Windows automatically joins the appropriate Active Directory site.

importantImportant:
This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore the registry if a problem occurs. For information about how to restore the registry, view the "Restore the Registry" Help topic in Regedit.exe or Regedt32.exe.
To remove the SiteName registry value
  1. Open a registry editor, such as Regedit.exe or Regedt32.exe.

  2. Navigate to: HKLM\System\CurrentControlSet\Services\Netlogon\Parameters

  3. In the right pane, locate and delete the SiteName registry value.

  4. Close the registry editor, and restart the server to have the change take effect.
