EVT_WDSMCS_E_NSREG_START_TIME_IN_PAST

EVT_WDSMCS_E_NSREG_START_TIME_IN_PAST is a Windows Deployment Services (WDS) Multicast Server result. It indicates that registration rejected a ScheduledCast namespace whose configured start time is no longer valid.

What to check for EVT_WDSMCS_E_NSREG_START_TIME_IN_PAST

  • Validate the scheduled time and time zone before registering the namespace.
  • Check clock synchronization on the management host and WDS server when timestamps appear correct.
  • Register a new transmission time far enough in the future for clients to join.

Diagnostic interpretation of EVT_WDSMCS_E_NSREG_START_TIME_IN_PAST

EVT_WDSMCS_E_NSREG_START_TIME_IN_PAST has the HRESULT value 0xC1210300. AllStat records the condition as “The ScheduledCast namespace %1 using content provider %2 could not be registered as it starts in the past. For EVT_WDSMCS_E_NSREG_START_TIME_IN_PAST, the namespace has been removed from the namespace store. %n %n Error Information: %3 %n”. For EVT_WDSMCS_E_NSREG_START_TIME_IN_PAST, in practice, interpret that wording at the boundary owned by Windows Deployment Services, rather than treating the value as a generic Windows message.

Evidence to capture for EVT_WDSMCS_E_NSREG_START_TIME_IN_PAST

  • Record the exact COM method or Windows API, its input object, the calling thread, and the full 0xC1210300 value before a wrapper converts it to an exception or Boolean result.
  • Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions EVT_WDSMCS_E_NSREG_START_TIME_IN_PAST or the evt / wdsmcs / nsreg / start / time operation.
  • Preserve the first failure in the call chain; a later HRESULT can describe cleanup rather than the original evt / wdsmcs / nsreg / start / time condition.

Retry and recovery for EVT_WDSMCS_E_NSREG_START_TIME_IN_PAST

Retry EVT_WDSMCS_E_NSREG_START_TIME_IN_PAST only when the owning API documents a transient state or after the condition described as “The ScheduledCast namespace %1 using content provider %2 could not be registered as it starts in the past. For EVT_WDSMCS_E_NSREG_START_TIME_IN_PAST, the namespace has been removed from the namespace store. %n %n Error Information: %3 %n” has changed. For EVT_WDSMCS_E_NSREG_START_TIME_IN_PAST, configuration, policy, format, and authorization failures normally require correction first; an immediate loop can hide the original call site and add secondary errors.
