Windows uses a new time synchronization service to synchronize the date and time of computers on a Windows-based network. Synchronized time is critical in Windows because the default authentication protocol (Kerberos version 5) uses workstation time as part of the authentication ticket generation process. The Windows Time Synchronization service (W32Time) is a fully compliant implementation of the Simple Network Time Protocol (SNTP) as detailed in IETF RFC 1769 viewable at the following Web site:
MessageId=0x33 Severity=Error SymbolicName=MSG_SOCKET_FAILED Language=English Invalid socket (TCP/IP might not be loaded)
MessageId=0x34 Severity=Error SymbolicName=MSG_NTP_NAME Language=English gethostbyname failed for server %1 (NTP or USNO)
MessageId=0x35 Severity=Error SymbolicName=MSG_BAD_SIGNATURE Language=English NTP server %1 (%2) returned an incorrectly signed time stamp.
MessageId=0x36 Severity=Error SymbolicName=MSG_NO_DC_LOCATED Language=English The Windows Time Service was not able to find a Domain Controller. A time and date update was not possible.
MessageId=0x37 Severity=Informational SymbolicName=MSG_NEW_DC_LOCATED Language=English New DomainController time source is %1 (%2) located in %3
MessageId=0x38 Severity=Error SymbolicName=MSG_BAD_DC_SIGNATURE Language=English The Domain Controller %1 (%2) in %3 returned an incorrectly signed time stamp. If this\nDC is from the machine's parent domain then the trust link between the domains may be broken and must be fixed. If the DC is from this machine's own domain, then the machine password for this machine is incorrect and should be corrected.
MessageId=0x39 Severity=Error SymbolicName=MSG_NODLL_IN_REGISTRY Language=English Service configuration is for a third-party DLL but the DLL name is not in the registry.
MessageId=0x3a Severity=Error SymbolicName=MSG_DLL_LOAD_FAILED Language=English The DLL for time sync does not have the proper entry point.
MessageId=0x3b Severity=Warning SymbolicName=MSG_NO_XSUM Language=English The NetLogonComputeServerDigest call returned an error. This is an internal failure but it will prevent this machine from providing correctly signed time.
MessageId=0x3c Severity=Warning SymbolicName=MSG_NTPNOXSUM Language=English The NTP time source %1 (%2) returned an unsigned time stamp. This likely means that the server experienced an internal failure. Please check the event log on that server.
