WSAEREMOTE
WSAEREMOTE does not mean “the socket has a remote peer.” It is a compatibility-style condition stating that an item is remote or not locally available. That distinction is important because every connected TCP socket has a remote endpoint without this being an error.
Why the source API is essential
Microsoft keeps BSD-oriented constants in the Winsock error namespace, while warning that some defined values are not returned by any Windows Sockets function. A portable library, redirected filesystem operation, or provider can therefore surface WSAEREMOTE through a common error-reporting layer.
Diagnostic questions
- Was the failing operation actually a socket call, or a file/object operation performed by network software?
- Did the code require a local object, local metadata, or a local-only operation?
- Was the path redirected to a share, distributed filesystem, or provider namespace?
- Which module translated the original error into a
WSA*value?
Do not treat the code like WSAENETUNREACH or WSAEHOSTUNREACH. Those describe reachability; WSAEREMOTE describes object locality semantics.
