  See help for Get-WMIObject cmdlet.. you need to use parameter to specify remote computer name which you're not using. so, for each loop iteration, it is running on local system only, giving you same results

  Hi,

  >>What can I do to rectify the RPC Server is unavailable?

  RPC server is unavailable also contains many reasons.

  First of all, you need to consider the firewall settings for RPC related ports, you could open firewall find out the RPC related rules to check.

  Second, if you wanted to bypass this error you could do like this:

  $servers = Get-Content c:\temp\test.txt 
  foreach($ser in $servers)
  {
      if(Test-Connection -ComputerName $ser)
      {
         Get-WmiObject -cn $_ win32_operatingsystem | select csname,Version 
      }else{
          Write-Host "connect to remote server failed!"
      }
  }
  OR:
  
  Get-Content c:\temp\test.txt | Invoke-Command -ComputerName $_.servername -ScriptBlock{ Get-WmiObject win32_operatingsystem | select csname,Version}`
  -ErrorAction SilentlyContinue -Credential contoso\admin

  Best regards,

  Andy
