Connecting to remote server failed with the following error message : WinRM cannot complete the operation

Question

 

when I run the following powershell script:

$FarmAcct = 'domain\user' 
$secPassword = ConvertTo-SecureString 'aaa' -AsPlaintext -Force 
$global:farmCredential_ = New-Object System.Management.Automation.PsCredential $FarmAcct,$secPassword
Invoke-Command -ComputerName "172.21.4.14" -Credential $global:farmCredential_ -Scriptblock { write-host "HELLO"}

Got this error:

Connecting to remote server 172.21.4.14 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.
    + CategoryInfo          : OpenError: (172.21.4.14:String) [], PSRemotingTransportException
    + FullyQualifiedErrorId : WinRMOperationTimeout,PSSessionStateBroken

I have install winrm feature and execute "enable-psremoting -force".

Anybody know how to fix it, thanks in advance.

BTW:I think this issue is more related to Windows PowerShell, I suggest you posting this thread to Windows PowerShell Forum.
