WCF Funktioniert zwischen verschiedenen Computern, aber nicht auf demselben Computer

Question

Ich habe einen WCF-Dienst, der auf Maschine B ausgeführt wird, und einen Client auf Maschine A. Diese Remoteverbindung funktioniert einwandfrei. Ich habe keine app.config-Datei, da alle Verbindungen über Code erfolgen. Ich benutze Tcp.

Das Problem tritt auf, wenn ich versuche, den Server und den Client auf dem gleichen Computer auszuführen. Ich bekomme die Ausnahme: The Server has rejected the client credentials. mit innerer Ausnahme: The logon attempt failed Warum schlägt das fehl, wenn ich den Client und den Server auf demselben Computer stelle?

Answer 1

versuchen, den Dienst mit der internen IP von Maschine B Zugriff (192,168 ...).

Wenn Probleme immer noch auftreten, bedeutet dies wahrscheinlich, dass etwas mit der IIS-Serverauthentifizierung zusammenhängt. Das bedeutet, dass nur Computer A die Berechtigung hat, eine Verbindung zu Ihrem Server herzustellen (z. B. Windows-Authentifizierung oder bestimmte Benutzer).

Wenn es mit der internen IP funktioniert, blockiert etwas auf Maschine B Anfragen von localhost (127.0.0.1). Möglicherweise müssen Sie die erweiterten Firewalleinstellungen oder die IIS-Serverkonfigurationen überprüfen.
