Windows 2008 CA: Error 401 – Access is denied

by luca

Windows Server’s Certification Authority offers a web interface to request certificates, available at the following URL: https://nomeserver/CertSrv.

When I tried to connect to an Enterprise CA installed on a Windows 2008 server, I got this error message: 401 – Unauthorized: Access is denied:

Open the IIS management console, select CertSrv virtual directory and click Authentication:

Choose Windows Authentication and, on the right, Providers…:

Select NTLM and click Move Up, to move that element to the top of the list:

After having restarted IIS, you can connect to CA’s web interface:
