Try this one:<br />

<pre><code class="code-1 nolinks" id="code-20-43056184-1"><span>(Get-ADComputer -Filter *).Name | Foreach-Object {Get-CimInstance Win32_Bios -ComputerName $_ -ErrorAction SilentlyContinue | Select-Object PSComputerName,SerialNumber}</span>

Hi @hello There,<br><br>Thank you for your suggestion. I tried the script and it showed the machine names and serial number of machines but it does not proceed after that and it is still running without any output.
</div>


<div>
I tried the below script and I am getting RPC unavailable error message.<br><br>$computer = Get-Content c:\ADComputers.txt<br>$Output = Foreach($C in $computer){<br>&nbsp; &nbsp; $System = Get-WmiObject Win32_ComputerSystem -ComputerName $C | Select-Object -Property Name,Model<br>&nbsp; &nbsp; $BIOS = Get-WmiObject Win32_BIOS -ComputerName $C | Select-Object -Property SerialNumber<br>&nbsp; &nbsp;[PSCustomObject]@{<br>&nbsp; &nbsp; &nbsp; &nbsp; ComputerName = $C<br>&nbsp; &nbsp; &nbsp;&nbsp;Name = $System.Name<br>&nbsp; &nbsp; &nbsp;&nbsp;Model = $System.Model<br>&nbsp; &nbsp; &nbsp; &nbsp; SerialNumber = $BIOS.SerialNumber<br>&nbsp; &nbsp;}<br>}<br>$Output<br><br>$Output |Export-Csv -Path c:\pstest\Result.csv -NoTypeInformation<br><br>Get-WmiObject : The RPC server is unavailable.

It's possible that the device is not turned on or so.<br />
<br />
This one also works for me.<br />

<pre><code class="code-1 nolinks" id="code-20-43056385-1"><span>$computers = get-adcomputer -filter * | select-object -expandproperty Name</span>
<span>foreach ($computer in $computers) {</span>
<span>$serial = Get-WMIObject -Class Win32_BIOS -ComputerName $computer | select-object -expandproperty  SerialNumber</span>
<span>write-output (&quot;Computer {0} Serial Number: {1}&quot; -f $computer,$serial)</span>
<span>}</span>
</code></pre>
</div>


<div>
All the devices are turned ON but still I receive "The RPC server unavailable " message
</div>


<div>
