Hi guys,

When i use the scirpt i have this message at the end of the update of the deploymentshare.

About to run command: WDSUTIL /Replace-Image /Image:"Lite Touch Windows PE (x86)" /ImageType:Boot /Architecture:x86 /ReplacementImage /ImageFile:"C:\Users\tissirm\AppData\Local\Temp\32\MDTUpdate.10468\ISO\Sources\Boot.wim" WDSUTIL rc = -1056702168 Exit code = 1

Powershell and I even got the image name! WDSUTIL doesn't seem to mind spaces in it's command line structure (odd but this script fails when I used quotes). Not bad for my first crack at Powershell scripting.

# The script:

#------------------------------

$Stage = (Get-ChildItem env:STAGE).value

If ($Stage -eq "ISO") {

$DeployRoot = (Get-ChildItem env:DEPLOYROOT).value

If ($DeployRoot -like "\\*\*") {

$DeploymentServer = $DeployRoot.split("\")[2] }

Else {

$DeploymentServer = (Get-ChildItem env:ComputerName).value

}

# Note that this script is called once for each platform image created (x86, x64)

$Platform = (Get-ChildItem env:PLATFORM).value

$Content = (Get-ChildItem env:CONTENT).value

# Determine the Name of the existing .wim file that exists in the WDS Share

$WDS_Share = "\\$DeploymentServer\" + (get-wmiobject win32_share -computername $DeploymentServer | where-object {$_.name -eq "REMINST"}).name

$ImageFileName = "$WDS_Share\Boot\$Platform\Images\" + (dir "$WDS_Share\Boot\$Platform\Images" *.wim).name

# Grab the 'Friendly Name' of the WDS Image File

$ImageName = (((wdsutil /get-imagefile /imagefile:$ImageFileName | select-string -inputobject {$_} -pattern "Image name:*").ToString()).split(":")[1]).trim()

# Run WDSUTIL to load the image on the server being updated.

WDSUTIL /replace-image /image:$ImageName /ImageType:Boot /Architecture:$Platform /ReplacementImage /ImageFile:$Content\LiteTouchPE_$Platform.wim /Server:$DeploymentServer

}

#------------------------------

then adjust LiteTouchPE.xml:

<Exits>

<Exit>Powershell.exe "%deployroot%\Scripts\WDSupdate.ps1"</Exit>

</Exits>

This script worked great until I created my first remote deployment share. When I updated the remote share's Boot.wim, The scripts stepped up and replaced my local boot images.

This resulted in local PXE boot.wim files that set the deployroot to the remote server share. Worked great but, very slow of course :)

I think I'll end up disabling the extension in the LiteTouchPE.xml file on the remote share and manually replacing files on those machines.

If I knew powershell, I think the solution would revolved around remote execution of WDSutil on the server specified in the DEPLOYROOT variable.

Hi Michael,

I just wanted to add some additional information about this process. In fact, because there isn't a "POSTWIM" phase it is necessary to do these automated process during "POSTISO" phase and require that "Generate a Lite Touch bootable ISO image" option have been enabled (for LiteTouch Image)

In addition it is required to have already added these boot images in WDS manually at least one time.

is it true ?
