SYMPTOMS
When you move a server that is running Microsoft Exchange Server 2007 from one organizational unit (OU) to another OU, the following event is logged in the Application log. Event Type: Warning

Event Source: MSExchangeSA

Event Category: General

Event ID: 9186

Description:

Microsoft Exchange System Attendant has detected that the local computer is not a member of group '/dc=/dc= /ou=Microsoft Exchange Security Groups/cn=Exchange Servers'. System Attendant is going to add the local computer into the group.

The current members of the group are 'CN=Exchange 12 Domain Servers,CN=Microsoft Exchange System Objects,DC= ,DC=; CN= ,OU=Servers,DC= ,DC=; CN=Exchange 12 Domain Servers,CN=Microsoft Exchange System Objects,DC= ,DC=; CN=Exchange 12 Domain Servers,CN=Microsoft Exchange System Objects,DC= ,DC=; '. For more information, click http://www.microsoft.com/contentredirect.asp.

Event ID 9186 is logged even though the Exchange 2007 server is a member of the Exchange Domain Servers group.



CAUSE
When the System Attendant service starts, it caches the distinguished name of the local server. The distinguished name of Exchange server changes when the Exchange server is moved from one OU to another OU. The new distinguished name differs from the distinguished name in the cache. Therefore, the System Attendant service logs event ID 9186 in the Application log on the Exchange server.



RESOLUTION
To resolve this issue, restart the System Attendant service to update the cached value.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
