When the Active Directory Auto Agent Assignment feature of System Center Operations Manager 2007 is enabled, event 11470 is logged every hour on the Root Management Server. This symptom occurs because the <Server>_PrimarySG_<number> security group is repopulated when Active Directory is requeried.
If the list of computers from Active Directory has not changed since the last query, the group should not be repopulated. However, if the number of computers that is returned by the LDAP query from Active Directory exceeds 1500, the security group will be repopulated.
System Center Operations Manager 2007 event 11470 resembles the following:
Source: Health Service Modules Category: None Type: Informational Event ID: 11470 Description: AD Assignment module successfully added N computers to SecurityGroup <server>_PrimarySG_<number> in domain <domain_name> since the result of the assignment LDAP query has changed.
