Powershell remoting problem

This is the powershell script I am executing in my client pc.

Set ExecutePolicy Unrestricted

$secureString=convertto-securestring "mypass56" -AsPlainText -Force

$credentials = new-object -typename System.Management.Automation.PSCredential -argumentlist "bordingvista.com.bd.local\tih",$secureString

Invoke-Expression -ComputerName svrtst021-vpc -port 80 -credential $credentials -Command "c:\scrtipts\Remote.ps1"

The Error I am getting is:

Invoke-Expression : [svrtst021-vpc] The WinRM client cannot process the request. The WinRM cl
ient tried to use Kerberos authentication mechanism, but the destination computer (svrtst021-vpc.bordingvista.com.bd.lo
cal:80) returned an 'access denied' error. Change the configuration to allow Kerberos authentication mechanis

eported by server: Negotiate

+ Invoke-Expression <<<< -ComputerName svrtst021-vpc -port 80 -credential $credentials -Co
mmand "c:\scrtipts\Remote.ps1"

svrtst021-vpc is a virtual pc which is connected to the same domain, that my client pc is connected to.Can anyone give any solution?
