EVT_WDSMCS_E_CP_CLOSE_INSTANCE_FAILED
EVT_WDSMCS_E_CP_CLOSE_INSTANCE_FAILED is a Windows Deployment Services (WDS) Multicast Server result. It indicates that the provider returned an error while WDS Multicast Server attempted to close an existing instance.
What to check
- Check for active sessions, outstanding callbacks, and content handles that prevent orderly shutdown.
- Log the provider-specific close error and instance identity before the reference is discarded.
- Correct provider cleanup sequencing so repeated close or service restart operations remain safe.
