Can not connect to remote pc with powershell - powershell

Question

I connect from one computer to another remote computer with powershell.
For this to work I did some configuration on both computer according to this video:
https://technet.microsoft.com/en-us/itmanagement/ff765030.aspx
But still I get an error message when I try to do this on the local computer:
enter-pssession -comp remotePC -credential domain\username
Then I enter the password and hit enter.
I get this error:
Connecting to remote server LocalPC failed with the following error message :
The WS-Management service cannot process the request. The
service is configured to not accept any remote shell requests. For more
CategoryInfo : OpenError: (LocalPC:String) [], PSRemotingTrans
portException + FullyQualifiedErrorId : RemoteSessionDisallowed,PSSessionStateBroken
The "Windows Remote Management"-Service is started on the remote PC.
I totally disabled the firewall for test purpose totally on the remote PC.
I did also enable-psremoting and Set-Item WSMan:\localhost\Client\TrustedHosts *
When I execute on the remote PC:
winrm config it says:
WinRM service is already running on this machine.
WinRM is already set up for remote management on this computer.
What else of that 1000 things do I still have to enable that I can connect to my remote pc with powershell?

Answer 1

As you can see from dir WSMan:\localhost\Shell\ output:
Type Name SourceOfValue Value
---- ---- ------------- -----
System.String AllowRemoteShellAccess GPO false
WS-Management configuration property AllowRemoteShellAccess have value false with source GPO. That means: group policy applied to target computer does disallow remote shell access.
