WinRM cannot complete the operation. Verify that the specified computer name is valid

When I try to fetch the service information on remote computer I got an WINRM error.

 PS C:\Windows\system32> invoke-command -computername Node1 -ScriptBlock {gsv}
 [Node1] Connecting to remote server Node1 failed with the following error      
 message : WinRM cannot complete the operation. Verify that the specified computer 
 name is valid, that the computer is accessible over the network, and that a firewall 
 exception for the WinRM service is enabled and allows access from this computer. By 
 default, the WinRM firewall exception for public profiles limits access to remote computers
 within the same local subnet. For more information, see the about_Remote_Troubleshooting Help topic.
