An anonymous session connected from 192.168.6.60 has attempted to open an LSA policy handle on this machine. The attempt was rejected with STATUS_ACCESS_DENIED to prevent leaking security sensitive information to the anonymous caller.
The application that made this attempt needs to be fixed. Please contact the application vendor. As a temporary workaround, this security measure can be disabled by setting the \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\TurnOffAnonymousBlock DWORD value to 1.
