  Salve,

  lavoro presso un cliente e tramite il mio portatile mi connettevo alla rete aziendale attraverso una connessione Ethernet fornendo le mie credenziali (username, password e Dominio). Da circa una settimana l'autenticazione alla rete mi fallisce e non riesco più a connettermi. Non mi compare più la popup di autenticazione. Riporto il dettaglio dell'errore che ho visualizzato tramite l'event viewer:

  - <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">

  - <System>

    <Provider Name="Microsoft-Windows-Wired-AutoConfig" Guid="{b92cf7fd-dc10-4c6b-a72d-1613bf25e597}" />

    </EventData>

    </Event>

   

  Riporto inoltre l'output di alcuni comandi sulle interfacce di rete:

  netsh lan>show interfaces

  There are 3 interfaces on the system:

  netsh lan>show settings

  Wired LAN settings
  ---------------------
      Auto connection logic is enabled on interface "Local Area Connection"
      Auto connection logic is enabled on interface "Local Area Connection* 21"
      Auto connection logic is enabled on interface "Local Area Connection 2"

  
  netsh lan>show tracing
  Wired tracing is currently stopped.

   

  Avete un'idea di cosa possa essere successo?

  Il mio account sulla rete aziendale non è scaduto...attraverso altri PC riesco a connettermi alla rete.

   

  Grazie

  Marco
