Manage Windows Server 2008 R2 from Window Server 2012

So when you started with Windows Server 2012 in the event op this server you see perhaps the following issues:

Server Manager 2012 with errors


Server Manager 2012 with errors

In this situation the other servers are Windows Server 2008 R2.

The reason in short is that the Windows Server 2008 R2 machines don’t have

  • .NET Framework 4.0 and
  • not the latest WMF

In the following article you can find the solution how you can solve this which also drops the notifications you see at your Windows Server 2012 Server Manager console.

How I forgot to tell you one important issue. When your server is Windows Server 2008 R2 you need this versions of WMF 3.0.

Also I execute the following arguments on the servers with the errors:

winrm quickconfig -quiet
winrm set winrm/config/service @{AllowUnencrypted=”true”}
winrm set winrm/config/service /auth @{Basic=”true”}
winrm set winrm/config/client  @{AllowUnencrypted=”true”}
winrm set winrm/config/client  @{TrustedHosts=”*”}
