Fix: Windows Update Fehler 0x80072f0c mit WSUS Server

Nach einer Neuinstallation des WSUS Servers bin ich auf folgenden Fehler bei einigen Windows Clients gestoßen: 0x80072f0c
Der Fehler bedeutet dass ein Zertifikat für die Authentifizierung notwendig ist. (A certificate is required to complete client authentication)
Besitzt der Client der Updates beziehen möchte also ein Computerzertifikat sollte es funktionieren.
Jedoch benutzt nicht jeder Computerzertifikate, also kann man den Authentifizierungstyp im IIS auch abändern.

  1. Internet Information Services (IIS Manager) starten
  2. Zur Site „WSUS Administration“ wechseln
  3. SSL Settings öffnen
  4. Prüfen dass kein Haken bei „Require SSL“ gesetzt ist und Client Certificates auf „Ignore“ steht.
  5. ggf. per cmd noch einen iisreset machen
