I am trying to use the online Certificate Authority service to generate a certificate.
When I browse to http://127.0.0.1/CertSrv
I recive the following error message:
Server Application Unavailable
The web application you are attempting to access on this web server is currently unavailable. Please hit the "Refresh" button in your web browser to retry your request.
Administrator Note: An error message detailing the cause of this specific request failure can be found in the application event log of the web server. Please review this log entry to discover what caused this error to occur.
This is what gets logged in the application > event viewer:
A request mapped to aspnet_isapi.dll was made within an application pool running in Integrated .NET mode. Aspnet_isapi.dll can only be used when running in Classic .NET mode. Please either specify preCondition="ISAPImode" on the handler mapping to make it run only in application pools running in Classic .NET mode, or move the application to another application pool running in Classic .NET mode in order to use this handler mapping.
Source: ASP.NET 4.0.30319.0
Event ID: 1324
How can I fix this?
