NS_I_RECONNECTED

Where the result originates

NS_I_RECONNECTED means the legacy Windows Media client restored its connection after an interruption.

The result comes from the network client session that transitions back to connected state. A representative case is a unicast client reopens its transport and resumes from a server-selected point after a transient link loss.

Read the call sequence as a timeline. First, the application reaches the network client session that transitions back to connected state. Next, the component evaluates the legacy Windows Media client restored its connection after an interruption. A wrapper, user interface, or fallback path can report a less specific message afterward.

Evidence that survives retries

  • Exact request: method name, all identifiers, units, flags, stream number, requested action, and this result.
  • Object state: disconnect and reconnect timestamps, protocol, server endpoint, stream position, packet loss, buffering state, and whether a new session ID was issued.
  • Correlation: callback cookie, object instance, URL or file identity, device identity, and timestamps from the same attempt.
  • Underlying cause: the first Win32, COM, network, driver, policy, or component error reported before 0x400D2EFF.

A controlled verification sequence

Use one controlled experiment: introduce a brief controlled network interruption and verify continuity, resubscription, and timestamp behavior after reconnect. A useful comparison for this result changes exactly that variable; changing content, account, proxy, device, components, and version together makes attribution impossible.

OutcomeInterpretation
The same operation now succeedsThe changed precondition was relevant to the failure.
A more specific earlier HRESULT appearsPreserve it; this result was probably a wrapper or terminal state.
The operation advances and fails laterThe condition is fixed even though the complete workflow still has another defect.
No behavior changesRestore the original baseline and test another documented prerequisite instead of stacking workarounds.

Nearby results that mean something else

Related codeWhy it is not interchangeable
NS_I_EXISTING_PACKETIZERThere is already an existing packetizer plugin for the stream.
NS_I_MANUAL_PROXYThe proxy setting is manual.
NS_E_NO_MULTICASTNot receiving data from the server.

The important distinction is this: NS_E_NO_MULTICAST means data is still absent; reconnect indicates the transport session has recovered. Use the symbolic constant and 0x400D2EFF value to distinguish states that share a similar visible message.

Repair at the owning layer

Apply the narrow remedy: treat the value as an informational recovery event and verify media continuity rather than displaying it as a fatal error. Then discard stale media objects, pending callbacks, cached provider sessions, or installer state as appropriate and rerun the exact request that originally returned it.
