Verify WinRM 3.0 service is installed, running, and required firewall ports are open
Windows Server 2008 R2
Management from 2012 Server Manager return the error:
Windows Server 2008 R2: Verify WinRM 3.0 service is installed, running, and required firewall ports are open
To narrow down this issue, would you check if have you installed both Windows Management Framework 3.x and .NET Framework 4.x in Windows Server 2008 R2 SP1? If not, get the appropriate .msu from the following link and install them on Windows Server 2008 R2 SP1:
Windows Management Framework 3.0
Microsoft .NET Framework 4.5.1 (Offline Installer) for Windows Vista SP2, Windows 7 SP1, Windows 8, Windows Server 2008 SP2 Windows Server 2008 R2 SP1 and Windows Server 2012
After that, run winrm qc from PowerShell or cmd prompt and check is it persists.
If the issue persists
Running winrm id to see if WinRM was all installed correctly on each server.
Use netsh advfirewall firewall show rule name="Windows Remote Management (HTTP-In)" to verify that the firewall rules had port 5985 open on our current NLA profile.
Use netstat -a -b to confirm that if there is any local process that was actually bound to port 5985.
Finally, please run winrm enumerate winrm/config/listener to confirm that if WinRM is actually listening on the port.
