We recently had an issue where an Exchange 2003 server failed to dynamically discover its site membership. After a reboot the server would bind to a out-site-domain controller and some exchange services would not start. The error below was also seen:

Event Type: Error
Event Source: MSExchangeSA
Event Category: General
Event ID: 1005
Unexpected error No site name is available for this machine. Facility:
ID no: c007077f Microsoft Exchange System Attendant


Manually set the site membership by making the following registry change:

  1. Start Registry Editor, Regedit.exe.
  2. Locate and click the following registry key:


  3. Double-click the SiteName value, and then type the site name (as it is configured in Active Directory) in the Value Data box.NOTE: If the SiteName value does not exist, follow these steps to create it:
    1. On the Edit menu, point to New, and then click String Value.
    2. Type SiteName to change the name of the newly created value, and then press ENTER.
    3. Double-click the SiteName value, and then type the site name in the Value Data box.
  4. Quit Registry Editor.
  5. Restart the computer.
