IIS - The request failed with HTTP status 401: Unauthorized.

[full-mann 10]

Hai,

 

ich versuche gerade eine Seite auf unserem IIS-Server (7.5.7600.16385) wieder ans laufen zu bekommen. Warum Sie nicht mehr funktioniert wissen wir nicht. Laut dem Server-Verantwortlichen wurde nichts geändert.

 

Der Server folgt folgendes an, wenn wir die Seite aufrufen möchten:

 

Server Error in '/helpLinePortal' Application.
