Workaround
Re-enable the AD Driver CAADFlt.sys by navigating to the following registry folder:
Path: HKEY_LOCAL_MACHINE\SOFTWARE\Quest Software\ChangeAuditor for Active Directory\
Change the DisableADDriver Key to the following:
Value Name: DisableADDriver
Value Type: DWORD
Change the Value From : 1 (Disable AD Driver)
Change the Value To : 0 (Enable AD Driver, default)
Once the registry key has been updated, it is necessary to restart the agent service.
