Web application Proxy on-premises Non-Responsive
We had a recent issue with Web Application Proxy throwing an error 'Maximum no. of Kerberose Attempts exceeded' with error 12008 in WAP server resulting it in being non-responsive. A case has been opened with MS with regards to this as well. When this issue happened WAP server could not authenticate any user. Only resolution was to restart both IIS and WAP Server. This was caused due to left over ghost entries in teh ApplicationHost.config file for the winodws authentication. This issue needs to be addressed in the product as its an issue that can reoccure if the web applications are not deleted properly from ApplicationHost.config file.
