NS_E_CANNOTCONNECTEVENTS
NS_E_CANNOTCONNECTEVENTS — 0xC00D006F
Diagnosing NS_E_CANNOTCONNECTEVENTS
NS_E_CANNOTCONNECTEVENTS identifies this Windows Media Services boundary: unable to establish a connection to the NetShow event monitor service.
Why this boundary matters
This HRESULT belongs to a specific network or control-path stage. Keep the resolved endpoint and selected protocol fixed, and preserve the first socket/protocol result so DNS, connection, negotiation, response parsing and media delivery are not collapsed into one generic network failure.
Evidence to collect
| Field | What to preserve |
|---|---|
| Peer | Resolved server/peer endpoint and the protocol actually selected for the request. |
| Stage | Last completed stage: resolution, connection, control exchange, response parsing or media delivery. |
| Transport result | First socket/protocol status, timeout/reset indication, and byte counts when data transfer started. |
| Intermediaries | Proxy, gateway or second Content Server involved in the same path, including its identity. |
Decision rule
Keep endpoint and protocol fixed while changing one network precondition; a later socket or parser result is a new boundary and should be diagnosed separately.
Focused test
Verify the NetShow event-monitor service state and endpoint, then capture the first connection or service-control error while connecting to that same event service.
Verification
Repeat the same request to the same endpoint with the same selected protocol. Confirm it passes the previously failing network stage; if it advances and fails later, diagnose the later socket/protocol result separately.
