The post Fixing Failed to Start and Configure the WSUS Service in Windows Server 2012 R2 first appeared on KC's Blog.]]> I upgraded one Windows Server 2008 R2 machine to Windows Server 2012 R2 the other day and had a bit hard time getting WSUS to work again. WSUS is now part of Windows Server 2012 family serving as a role, instead of a standalone software that needs to be installed separately in previous Windows.

After I successfully added WSUS as a service role to the server, I need to run the Post-installation process to complete the whole installation. And that’s where the issue started.

Fatal Error: Failed to start and configure the WSUS service

After looking at the log file indicated in the Notification window, here is what I found:

2016-12-21 10:06:27  CreateDefaultSubscription failed. Exception: System.InvalidOperationException: Client found response content type of 'text/html; charset=utf-8', but expected 'text/xml'.
The request failed with the error message:

         .expandable { text-decoration:underline; font-weight:bold; color:navy; cursor:hand; }
        </style>

It took me at least one hour to finally figure it out. It’s basically the setup in Application Pools in IIS that messed things up. To fix it up, open IIS Manager, head over to Application Pool, and set WsusPool to use .Net v4.0 instead of v2.0 in my case.

Once done, I started the Post-installation again and it went all the way to the end successfully without any further issues.

On another note, there is another different error that also causes post-installation to fail.

CreateDefaultSubscription failed. Exception: System.Net.WebException: The request failed with HTTP status 503: Service Unavailable.

If that’s the case for you, all you need to do is to remove WSUS Administration site in IIS and start the post-installation process again.

That’s about it. Hopefully, it helps.
