Hi This is not professional SBS forum. Fresh Exchange 2010 is difference from SBS2011. http://social.technet.microsoft.com/Forums/en-US/smallbusinessserver2011essentials/threads I can find similar case about SCOM. The event just means rum cmdlst Get-User {Identity=NT AUTHORITY\SYSTEM} fail. http://social.technet.microsoft.com/Forums/en-US/exchangesvravailabilityandisasterrecovery/thread/c663ad93-3712-45da-b7f9-d6d914ad71a5
