EVT_WDSMCS_E_CP_SHUTDOWN_FUNC_FAILED

EVT_WDSMCS_E_CP_SHUTDOWN_FUNC_FAILED is a Windows Deployment Services (WDS) Multicast Server result. It indicates that the provider returned an error while WDS Multicast Server was shutting it down.

What to check

  • Record the provider shutdown error and inspect open content, sessions, and worker threads.
  • Ensure the provider stops asynchronous work before releasing callbacks, handles, and shared resources.
  • Restart the WDS service only after preserving diagnostics needed to locate the provider cleanup failure.
