    Query :
    $Session = New-PSSession -ComputerName "Test" -Authentication CredSSP -Credential $Cred

    Error :

    How are these machines related? Are they in a domain together? Not in a domain? Is the destination computer's name exactly as listed in DNS and/or Active Directory?

    Also, what PowerShell versions are you running on the client and server?

      1. Both Client and Server is running on PS Version 3.0
      2. Both machines are on the same domain.
      3. Destination computer tried with both IP and Host name, am getting the same error.

    So, "Secrets of PowerShell Remoting" gets into some of these details, but...

    Why not just allow the default Kerberos protocol to be used? However, note that you must connect using the target's canonical AD name, in order for the mutual authentication to function. You can't use IP address unless you take different steps, because the computer can't be "found" in AD by IP.

    But CredSSP has a number of requirements; see the "Second Hop" section in And, double check the CredSSP configuration – the target must be in "Server" mode, the origination must be in "Client" mode, and must specify the server as a trusted delegate.
