Sccm task sequence error

what command / task are you running for the user to enter the username? show us the script you are running

this is what i enter at the sccm (task sequence) - powershell.exe -command “set-ExecutionPolicy Unrestricted; cpi %SCRIPTROOT%\OSDComputerNamePrompt.ps1 -destination c:\; c:\OSDComputerNamePrompt.ps1; ri c:\*.ps1; set-ExecutionPolicy restricted”


And this is the script within OSDComputerNamePrompt.ps1 :


function Load-Form {
    $Form.Controls.Add($TBComputerName)
    $Form.Controls.Add($GBComputerName)
    $Form.Controls.Add($ButtonOK)
    $Form.Add_Shown({$Form.Activate()})
    [void] $Form.ShowDialog()
}

function Set-OSDComputerName {
    $ErrorProvider.Clear()
    if ($TBComputerName.Text.Length -eq 0) {
        $ErrorProvider.SetError($GBComputerName, "Please enter a computer name")
    }
    else {
        if ($TBComputerName.Text.Length -gt 15) {
            $ErrorProvider.SetError($GBComputerName, "Computer name cannot be more than 15 characters")
        }
        else {
            $OSDComputerName = $TBComputerName.Text.Replace("[","").Replace("]","").Replace(":","").Replace(";","").Replace("|","").Replace("=","").Replace("+","").Replace("*","").Replace("?","").Replace("<","").Replace(">","").Replace("/","").Replace("\","").Replace(",","")
            $TSEnv = New-Object -COMObject Microsoft.SMS.TSEnvironment
            $TSEnv.Value("OSDComputerName") = "$($OSDComputerName)"
            $Form.Close()
        }
    }
}

Can you please elaborate ?

you can also do it directly in the task sequence

I am already using it as a task sequence, but i am getting an error when the script starts to run via the task sequencer.
please review my original post at the top again.

Hello,

Is there anything showing in the smsts.log that might indicate why it is failing?  Are you able to post a snapshot of the task sequence, specifically the step that is running the powershell script?

i dont see how \ where i get the smsts log file since i run the installation via USB into a blank SSD. (cant find any on the USB).

I would suggest that rather than using the 'Run command Line' step, you try using the 'Run PowerShell Script' step instead (as David suggested above):


This allows you to add a script from a package or add a script directly without the need of a package (don't forget to change the execution policy setting!):


Also, I would try running the step after the format and partition step but before the Apply OS step.

As for the smsts.log, that could be in one of several places.  See the link below:

I have tried moving it to a step before the OS step + running powershell script - still getting the error.
regarding the log file - the SSD is empty so there are no files there.

try reducing your script to

$computername = Read-host -Prompt "Input the Computer Name" 
Set-OSDComputerName = $computername

Tried that 2 lines script , still getting error.

what is the error?

Same error as at the start of this post.

Do you have Command Support enabled on the Boot Image (Boot Image properties -> Customization tab)?  If so you can hit F8 when the error occurs to bring up a command prompt.  From there you should be able to get to the WinPE drive (possibly x:\) where the smsts.log should be.

to use powershell the boot image also has to have .net framework added. This is from MDT which you should probably be using unless you support >1500 machines

"Do you have Command Support enabled on the Boot Image (Boot Image properties -> Customization tab)? "

I have enabled it and yet the f8 key does nothing at any phase during the task sequence run.

Do you have to use powershell?  We use a batch file for the same thing that works well for us.

No i dont have to use powershell.
Can you share your batch file solution please ?

Yes ! the vbs script worked like a charm !

Many thanks ! :)
