WDS Error - “Windows cannot install required files (…)”– Error code: 0x80070570 – Workaround

While I’m writing this post I’m just thinking that this really may help someone like it helped me last week.

First things first:

.: Microsoft it’s over this one because are a lots of clients complaining about it
.: This is not a solution but a workaround until Microsoft folks don’t find a real solution
.: I tested this solution over 3 different machines
.: Don’t know why but I’ve installed a new machine on VMware ESX and this problem didn’t happened
.: This happened to me when I’ve created a new machine and also when I deleted previous image from a WDS image group

Now…this is the scenario:

You install a brand new machine with Windows Deployment Services, you copy a wim file from another machine, not directly from RemoteInstall folder but from DeploymentShare\Captures for example, and when you try to deploy the image from the new machine you get an error like this one:

No matter what you do, you always get this error.

Now, the really strange thing here is that supposedly the wim file should contain every single file you need to do the deployment.

The workaround:

I’ve managed to workaround this issue using a simple solution.
I’ve copied the file Res.RWM located on every imagegroup, on a working machine to the new machine. This file exists at RemoteInstall\Images\ImageGroupName and it’s like an index file of all images that were published on the WDS.

What really intrigues me is that on a new machine the index just contains information about the first image you’ve put there, but well…that’s not enough.

Why? This is what Microsoft is investigating…

 

Just hope this helps everyone that’s getting crazy about this error.
As soon as I get any more info/solution about this, I’ll post it here.
