For some reason I was unable to view the websites that I previously published on this server, and access to the back end IIS server was not working.Let me show you how my lab environment is configured: My domain “” contains the following servers: The labiis server hosts a non-claims application which receives pre-authentication from labadfs using my AD DS account to log in.Hi All I'm having some issues narrowing down what is causing this issue.

When comparing the certificate thumbprint provided by the WAP Server event with the one used by the AD FS certificate, I noticed they were completely different: If you look at all certificate thumbprints, you won’t find any starting with “50571..” mentioned in the WAP server event.

After some research, I decided to do exactly what AD FS Event ID 276 says to do: Run the Install-Web Application Proxy cmdlet on the WAP server to re-establish trust between AD FS and WAP: The command above re-installs the correct certificate on the WAP Server.

Here's an explanation of each channel: Because administrators often encounter problems when creating clusters and joining nodes, I want to show you how to use the Failover Clustering-Client/Diagnostic channel.

This channel is disabled by default, so it won't be collecting any data.

Note that I’m using the correct certificate thumbprint (starting with 22121…): You need to provide your credentials in order to execute the cmdlet.

After running this cmdlet, the WAP server came back online and the configuration could be successfully retrieved from AD FS.Requests pass through labwap and then to labadfs for authorization.The user receives the AD FS authentication page requesting their AD DS credentials which forwards them to the IIS server (labiis).Additional Info Error 117 Solution 1: Check your clock on your computer.It cannot be off by more than 5 minutes from the web server Error 141 Solution 1: There are some new event channels for failover clustering to help with troubleshooting. Note that the events are specific to the node you're on.
