Suddenly I have this error when trying to access my application on IIS 8! Does anyone know how to fix it?

Answer 1

I had a similar issue and this article helped me resolve the issue: https://blogs.msdn.microsoft.com/prashant_upadhyay/2011/09/20/unable-to-expand-server-node-in-the-iis-7-ui-with-shared-configuration/

The issue in my case was the account associated with configurationRedirection was locked, once enabled the issue was resolved.

I guess a similar issue would arise if the account did not have access to the Shared configuration folder, or if the account's password/credentials had changed.

Answer 2

I had the exact same error message for one of my users following a permissions change to his user account. Turned out he had an old "disconnected" RDP session on the server. Once that was signed off (via task manager) the error went away.
