Event Information"According to Microsoft:
CAUSE :

This issue occurs if the following groups do not have sufficient permissions to the user objects in the Active Directory directory service:
• RTCHSDomainServices
• RTCDomainServerAdmins
• RTCDomainUserAdmins
This scenario may occur if you remove permission inheritance from the domain container in Active Directory before you install Live Communications Server.
Sometimes, this issue occurs because authenticated users may not have Read permissions for a user objects container and for the user objects in the container. If authenticated users has been removed or denied Read permissions, you must grant the RTCHSDomainServices group Read permissions on the user objects in the container and on the container.
