SCCM 2012 SP1 Management Point error "Call to HttpSendRequestSync failed for port 80/443 with status code 500, text: Internal Server Error"

Tell you what, I have to blame my sales team for this error. Let me explain, they like to push the latest and greatest and that's fine, until you forget old trick of the trade as you have been working with Windows Server 2012 since before it was officially launched ...

So, SCCM 2012 SP1 Management Prole on Windows Server 2008 R2, you need to register ASP.NET v4 with IIS. If you don't you will see the error below in your mpcontrol.log or in the System State Messages in the monitoring workspace.

Call to HttpSendRequestSync failed for port 80/443 with status code 500, text: Internal Server Error

Now I would like to point out that with SCCM 2012 pre SP1 this was never an issue as it uses .NET 3.5.

P.S you don't have to run this on Windows Server 2012 as it used .NET v4 by default.

Solution:

Run the following elevated command prompt on the affected Management Point.

cd /d %windir%\Microsoft.Net\Framework64\v4*
aspnet_regiis –i –enable

Any questions please ask.

Enjoy.
