Question

got below error when trying to connect to remote SharePoint server through power shell.
Steps:
Enable-WSManCredSSP -Role client -DelegateComputer servername.domain.com
winrm quickconfig
Enable-WSManCredSSP -Role server
$farm = Get-Credential
$s = New-PSSession -ComputerName servername.domain.com -Authentication CredSSP -Credential $farm
Invoke-Command -Session $s -ScriptBlock { add-pssnapin Microsoft.SharePoint.PowerShell -ea 0 }
Invoke-Command -Session $s -ScriptBlock { get-spfarm }
Invoke-Command -Session $s -ScriptBlock { get-spcontentdatabase }
Get-PSSession | Remove-PSSessioncmd
Error:
The WinRM client cannot process the request. The authentication mechanism requested by the 
client is not supported by the server or unencrypted traffic is disabled in the service configuration. Verify the 
unencrypted traffic setting in the service configuration or specify one of the authentication mechanisms supported 
by the server.  To use Kerberos, specify the computer name as the remote destination. Also verify that the client 
computer and the destination computer are joined to a domain. To use Basic, specify the computer name as the remote 
destination, specify Basic authentication and provide user name and password. Possible authentication mechanisms 
reported by server:     Negotiate Kerberos For more information, see the about_Remote_Troubleshooting Help topic.

Hi this is how I got it working:
For the Server:
On the domain controller open "Active Directory Users and Computers". Under "Computers" find the servername and right click properties, on Delegation Tab select "Trust this computer for delegation any service (Kerberos Only)"
And then from powershell:
$domainAdminCred = Get-Credential
 Start-Job -ScriptBlock {
        Enable-PSRemoting -Force 
  Enable-WSManCredSSP -Role Server -Force 
    } -Credential $domainAdminCred -Argumentlist servername.domain.com | Wait-Job | Receive-Job
Enable-WSManCredSSP -Role Client -Delegate servername.domain.com -Force
Connect-WSMan servername.domain.com
Set-Item "WSMan:\$server*\Service\Auth\CredSSP" -Value $true
$farm = Get-Credential
$session = New-PSSession -ComputerName servername.domain.com -Authentication CredSSP -Credential $farm
Invoke-Command -Session $session -ArgumentList $path -ScriptBlock {   
        if (-not(Get-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue))
            Add-PSSnapin Microsoft.SharePoint.Powershell
        Get-SPFarm
Hope it helps
