126.96.36.199 LsarOpenPolicy (Opnum 6)
The LsarOpenPolicy method is exactly the same as LsarOpenPolicy2, except that the SystemName parameter in this method contains only one character instead of a full string. This is because its syntactical definition lacks the [string] RPC annotation present in LsarOpenPolicy2, as specified in [C706]. RPC data types are specified in [MS-RPCE] section 188.8.131.52.
The SystemName parameter has no effect on message processing in any environment. It MUST be ignored.
NTSTATUS LsarOpenPolicy( [in, unique] wchar_t* SystemName, [in] PLSAPR_OBJECT_ATTRIBUTES ObjectAttributes, [in] ACCESS_MASK DesiredAccess, [out] LSAPR_HANDLE* PolicyHandle );
Processing rules for this message are defined in [MS-LSAD] section 184.108.40.206.2.
