WS_E_ADDRESS_IN_USE
WS_E_ADDRESS_IN_USE is a Windows Web Services API HRESULT. It means that the local address or endpoint needed by the listener or channel is already bound or otherwise unavailable for another use.
What to check for WS_E_ADDRESS_IN_USE
- Identify the process, listener or previous instance that owns the address and port.
- Check address reuse options, service startup races and stale listeners left after an unclean shutdown.
- Choose a valid alternate binding only when the application protocol and deployment configuration allow it.
Diagnostic interpretation
This result has the HRESULT value 0x803D000B. AllStat records the condition as “The address is already being used.”.
Evidence to capture
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions this result or the ws / address / in / use operation.
- compare the failing machine with a working one at the same configuration boundary: component version, policy, registration, identity, and target resource.
