Event ID: 6033
Event Source: LsaSrv
Event Type: Error
Event Description: An anonymous session connected from "LOCAL_COMPUTERNAME"
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.
