Enable Credential Security Service Provider (CREDSSP) authentication on the local client machine:

Enable-WSManCredSSP -Role client -DelegateComputer “SharePointServerName”

Open a credentials prompt box:

$cred=get-Credential 

Enter an administrators account (or the admin account you worked with in the Server Requirements) to run the rest of the PowerShell commands with this account.

Create a new remote session to the SharePointServerName using the authentication type CredSSP and the credentials previously entered:

$s=new-PSsession “SharePointServerName” - authentication credssp -credential $cred     

Load the SharePoint snap-in to the current session to allow SharePoint related scripts to be executed:

Invoke-Command -Session $s -ScriptBlock {Add-PSSnapin Microsoft.SharePoint.PowerShell;}

Return all content databases in your SharePoint farm (which ensures you have access):

Invoke-Command -Session $s -ScriptBlock {get-SPContentDatabase} 

Return all SharePoint service instances (which ensures you have access):

Invoke-Command -Session $s -ScriptBlock {get-spserviceinstance} 

To attempt to use the PS Session to ensure connectivity between the two machines

Enter-PSSession -session $s
