Windows Server 2012R2 Clustered Web Proxy Server

Question

We have two Windows Server 2012R2 Web Proxy Servers clustered and are planning to upgrade this year. The issue is on one of the server the Web Application Proxy service does not start and throws a 401 unauthorized error. The service does start and function on the primary server and i was not sure if that service is not running if not the primary server. If someone can help me answer that question i would be much appreciated.

Hello KMB72,

Thank you for your question and for reaching out with your question today.

In a clustered environment, the Web Application Proxy (WAP) service should run on all the nodes of the cluster. If the service is not starting on one of the servers, it can indicate a configuration or permissions issue specific to that server.

Here are some steps you can take to troubleshoot the issue:

1. Verify service startup: Ensure that the Web Application Proxy service is set to start automatically on the server where it's not starting. You can check this by going to "Services" in the Server Manager, finding the "Web Application Proxy" service, and confirming the startup type is set to "Automatic."
2. Check event logs: Examine the Event Viewer logs on the server where the Web Application Proxy service is failing to start. Look for any related error or warning messages that might provide insights into the cause of the issue. The Application and System event logs are good places to start.
3. Validate configuration: Verify that the server's configuration matches the configuration of the working server in the cluster. Check the network settings, certificates, firewall rules, and any other relevant configuration parameters to ensure they are consistent.
4. Verify service account permissions: Make sure that the service account used by the Web Application Proxy service has the necessary permissions. It should have appropriate rights and permissions to access the required resources, such as the necessary network resources and Active Directory objects.
5. Review proxy settings: Double-check the proxy server settings on the server where the Web Application Proxy service is failing. Ensure that the proxy settings are correctly configured, including any authentication or firewall settings that might affect the service.

By following these steps, you should be able to identify and resolve the issue preventing the Web Application Proxy service from starting on the affected server in your clustered environment.
