Okay so this is what happend :/
A client has a SBS 2011 Standard server where the certificate ran out. A genius decided to in order to fix this issue he would run the Set up your Internet Address Wizard. He configured it the first time with a wrong domain syntax. He then ran the wizard again to type in the correct information.
Now users are reporting that some get "No connection"
errors on shared calenders, its only 2 calenders at the moment.
When i run Autodiscover tests on a terminal server thats located as a vm inside the sbs 2011 machine i get errors:
When i browse to https://localhost/AUTODISCOVER
i get the following:
<?xml version="1.0" encoding="UTF-8"?>
-<Autodiscover xmlns="http://schemas.microsoft.com/exchange/autodiscover/responseschema/2006"> -<Response> -<Error Id="2600584124" Time="12:32:41.2274311"> <ErrorCode>600</ErrorCode> <Message>Invalid Request</Message> <DebugData/> </Error> </Response> </Autodiscover>
When i browse to https://127.0.0.1/AUTODISCOVER
i get an HTTP Error 500.0
Module: IIS Web Core
Error Code: 0x80070542
Most likely causes:
•IIS received the request; however, an internal error occurred during the processing of the request. The root cause of this error depends on which module handles the request and what was happening in the worker process when this error occurred.
•IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly.
•IIS was not able to process configuration for the Web site or application.
•The authenticated user does not have permission to use this DLL.
•The request is mapped to a managed handler but the .NET Extensibility Feature is not installed.
I really need some help here as i don't know how to repair the damage after this. Basically what i've found is that it seems Autodiscovery isn't working, resulting in the problems with the calenders.
