Explanation
This event message indicates that the msExchServerSite attribute in Active Directory has been updated by the Site monitor API. The Site monitor API updates the msExchServerSite attribute of the Microsoft Exchange server object when the local site name changes.
To reduce the overhead that's associated with DNS queries, the Microsoft Exchange Server 2010 Active Directory schema additions include the msExchServerSite attribute for the Exchange server object. The value of this attribute is the distinguished name of the Active Directory site of an Exchange server. This attribute is a property of each Exchange server object. When site membership affinity is stored as an attribute of the server object, the current topology can be read directly from Active Directory instead of relying on DNS queries. Also, a site membership association is enabled for a non-domain computer, such as a subscribed Edge Transport server.
