EVT_WDSMCS_E_CP_CALLBACKS_NOT_REG

EVT_WDSMCS_E_CP_CALLBACKS_NOT_REG is a Windows Deployment Services (WDS) Multicast Server result. It indicates that provider startup did not complete the callback registration expected by WDS Multicast Server.

What to check

  • Trace the provider initialization sequence and confirm every mandatory callback registration returns success.
  • Verify that a version mismatch did not change the callback contract or structure layout.
  • Do not register the provider for production namespaces until a clean initialization has been observed.
