SCVMM 2012: Getting WDS to work!

In SCVMM 2012- Preparing for Bare Metal Deployment, part 3, I looked at setting up WDS as one of the key parts to getting bare metal deployment to work.

One of the screens in the WDS configuration wizard is the PXE server initial settings:

In the blog posting, I said to leave that setting as “Do not respond to any client computers”. I said this because I was under the impression that the provider that VMM installs onto the WDS server would cause WDS to behave in the way it needs to behave for VMM.

That is not the case.

Indeed, it seems that setting the option to the middle choice – respond only to known client computers – is not the correct option either despite the fact that Microsoft explained that when the bare metal server does a boot from PXE, the PXE server talks to VMM to authorise the PXE boot.

In testing, it looks like the only way WDS will respond is if you set the option to the last choice – respond to all client computers (known and unknown). For my testing, I also selected the checkbox: require administrator approval for unknown computers. That way, you won’t suddenly get a bunch of systems trying to boot off your WDS server!

The setting can be changed retrospectively from the WDS console by right-clicking on the server, choosing Properties and then selecting the PXE Response tab:


I’ll post a separate blog showing the various stages that a bare metal server goes through as the deployment proceeds but hopefully the above change will get everything going for you.

    Great Post! In working with WDS in the past, i think the option “respond only to known client computers” only works for computers that pre-staged in Active Directory. I agree it doesn’t make sense for a bare-metal deployment….
    Thanks for the solution of using “respond to all client computers”

    I’ve found this is the case as well, but SCVMM only responds to PXE boots that are initiated by the Add Physical Computer as a Host Wizard. Meaning your PXE/WDS server can service both SCVMM BDM and standard PXE image deploys.
