    Hi All,

    Wondering if someone may be able to point to me where I am going wrong. I am trying to update Trend remotely however, when i run the script, it seems to only update Trend on the local machine in which i am running it and not on the remote machines as well.

    Thank you

    #Credentians for remote sessions
    $Cred = "USERNAME" 
    
    #Path To Trend
        $TrendPath = "c:\" ;cd "C:\Program Files (x86)\Trend Micro\OfficeScan Client"
    
    #Update Command
        $update = ./pccntmon -u
    
    #Creating Remote PS Session on Servers
      $RemoteServersSessions = New-PSSession -computername '10.2.34.34','10.2.34.35' -Credential $Cred
    
        
        Write-Warning "Open Remote PS Sessions" 
    #          $RemoteServersSessions
    
    # Invoking Remote Command to change path and update trend
        Invoke-Command -Session $RemoteServersSessions -ScriptBlock{$TrendPath; $update}
    
        Write-Warning "Trend on servers should now be updated"
        Write-Warning "Disconnecting remote Sessions"
    
    #Disconnect PS remote sessions
        Disconnect-PSSession -Session $RemoteServersSessions

    I think it's because the $trendpath and $update variables only exist in a local context, not on the remote machine. You can just pass those in as variables though, see the following for an example http://windowsitpro.com/powershell/using-variables-remote-powershell-sessions

      Hi Michael,

      I think you may be right. I see in Powershell v3 you can use "$using:BLA" however, I am not quite sure on how to incorporate that

        Snippet:
      Invoke-Command -Session $RemoteServersSessions -ScriptBlock {$Using:TrendPath; $Using:update}
        Full Script:
      #Credentians for remote sessions
      $Cred = "TEN\M0171512" 
      
      #Path To Trend
          $TrendPath = "c:\" ;cd "C:\Program Files (x86)\Trend Micro\OfficeScan Client"
      
      #Update Command
          $update = ./pccntmon -u
       
      #Creating Remote PS Session on Servers
        $RemoteServersSessions = New-PSSession -computername '10.2.34.34','10.2.34.35' -Credential $Cred
          
          Write-Warning "Open Remote PS Sessions" 
                $RemoteServersSessions
      
      # Invoking Remote Command to change path and update trend
          #Invoke-Command -Session $RemoteServersSessions -ScriptBlock{$TrendPath; $update}
          Invoke-Command -Session $RemoteServersSessions -ScriptBlock {$Using:TrendPath; $Using:update}
      
          Write-Warning "Trend on servers should now be updated"
          Write-Warning "Disconnecting remote Sessions"
      
      #Disconnect PS remote sessions
          Disconnect-PSSession -Session $RemoteServersSessions
