I am trying to create unattended.xml file for windows server 2016 unattended installation where in after installing windows it should execute one powershell script located on remote samba share.

I am using following command to run powershell script stored in samba share:

cmd.exe /c "ECHO R | powershell.exe -ExecutionPolicy Unrestricted -File \\192.168.137.131\install\ConfigureRemotingForAnsible.ps1"

The Unattended installation process works well but ConfigureRemotingForAnsible.ps1 script execution fails with error:

The argument '\\192.168.137.131\install\ConfigureRemotingForAnsible.ps1' to the -File parameter does not exist. Provide the path to an existing '.ps1' file as an argument to the -File parameter.

The same command executes successfully when I run it manually.

Relevant portion of unattended.xml file:

<settings pass="specialize">
        <component name="Microsoft-Windows-Deployment" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
            <RunSynchronous>
                <RunSynchronousCommand wcm:action="add">
                    <Order>1</Order>
                    <Path>cmd.exe /c "ECHO R | powershell.exe -ExecutionPolicy Unrestricted -File \\192.168.137.131\install\ConfigureRemotingForAnsible.ps1"</Path>
                </RunSynchronousCommand>
            </RunSynchronous>
        </component>
    </settings>

Can somebody tell me what should I add in my unattended.xml to make it working?

Thanks in advance.
