Unable to do PSSession into another remote desktop

I am trying to remote into another desktop using Powershell's Enter-PSSession to run a script automatically, however, i am not even able to connect to the remote desktop.

Enter-PSSession -Computername 172.16.164.14 -credential $cred

But it says access is denied. This is the error message:

Enter-PSSession : Connecting to remote server 172.16.164.14 failed with the 

following error message : Access is
denied. For more information, see the about_Remote_Troubleshooting Help topic.

    + CategoryInfo          : InvalidArgument: (172.16.164.14:String) [Enter-PSSession], PSRemotingTransportException

I also tried using:

Invoke-Command -ComputerName 7450-56Z0BP2 -FilePath -C:\user_automation\automate.vbs -credential $cred

where 7450-56Z0BP2 is the hostname, but the error it gave me is:

    [7450-56Z0BP2] Connecting to remote server 7450-56Z0BP2 failed with the following error message : WinRM cannot process
the request. The following error with errorcode 0x80090311 occurred while using Kerberos authentication: We can't sign
you in with this credential because your domain isn't available. Make sure your device is connected to your
organization's network and try again. If you previously signed in on this device with another credential, you can sign
in with that credential.
 Possible causes are:
  -The user name or password specified are invalid.
  -Kerberos is used when no authentication method and no user name are specified.
  -Kerberos accepts domain user names, but not local user names.
  -The Service Principal Name (SPN) for the remote computer name and port does not exist.
  -The client and remote computers are in different domains and there is no trust between the two domains.
 After checking for the above issues, try the following:
  -Check the Event Viewer for events related to authentication.
  -Change the authentication method; add the destination computer to the WinRM TrustedHosts configuration setting or
use HTTPS transport.
 Note that computers in the TrustedHosts list might not be authenticated.
   -For more information about WinRM configuration, run the following command: winrm help config. For more
information, see the about_Remote_Troubleshooting Help topic.

I am not sure what could be the cause of me not being able to access the remote computer. I am able to access it via Window 10's Remote Desktop Connection app, but i am not able to log in using the powershell script
