If you are running Microsoft Windows in a domain environment with WSUS configured, you may notice that you’re not able to install some FODs (Features on Demand), or use the “Turn Windows features on or off”. This will stop you from installing things like the RSAT tools, .NET Framework, Language Speech packs, etc…

You may see “failure to download files”, “cannot download”, or errors like “0x800F0954” when running DISM to install packages.

To resolve this, you need to modify your domain’s group policy settings to allow your workstations to query Windows Update servers for additional content. The workstations will still use your WSUS server for approvals, downloads, and updates, however in the event content is not found, it will query Windows Update.

Enable download of “Optional features” directly from Windows Update

  1. Open the group policy editor on your domain
  2. Create a new GPO, or modify an existing one. Make sure it applies to the computers you’d like
  3. Navigate to “Computer Configuration”, “Policies”, “Administrative Templates”, and then “System”.
  4. Double click or open “Specify settings for optional component installation and component repair”
  5. Make sure “Never attempt to download payload from Windows Update” is NOT checked
  6. Make sure “Download repair content and optional features directly from Windows Update instead of Windows Server Update Services (WSUS)” IS checked.
  7. Wait for your GPO to update, or run “gpupdate /force” on the workstations.

Please see an example of the configuration below:

Download repair content and optional features directly from Windows Update instead of Windows Server Update Services (WSUS)

You should now be able to download/install RSAT, .NET, Speech language packs, and more!

I’ve noticed an issue with Microsoft Windows Server 2016, where a default install, when joined to an Active Directory Domain, will not get it’s time from the domain itself, but rather from “time.windows.com”.

I first noticed this a couple months ago when I had some time issues with one of my Server 2016 member servers. I ran “net time” which reported time from the domain controller, so I simply restarted the VM and it resolved the issue (or so I thought). I did not know there was a larger underlying issue.

While performing maintenance today, I noticed that all Windows Server 2016 VMs were getting their time from “time.windows.com”. When running “w32tm /monitor”, the hosts actually reported the PDC time sources, yet it still used the internet ntp server. I checked all my Windows Server 2012 R2 member servers and they didn’t have the issue. All workstations running Windows 10 didn’t have the issue either.

When this issue occurs, you’ll notice in the event log that the Windows Time Service actually finds your domain controllers as time sources, but then overrides it with the internet server time.windows.com for some reason. The only reference you’ll find pertaining to “time.windows.com”, will be when you run the “w32tm /query /configuration” command.

We need to change the time source from that host to the domain “NT5DS” time source. We’ll do so by resetting the configuration to default settings on the member server.

How to reset the Windows Time Service (w32tm) to default settings

PLEASE NOTE: Only run this on member servers that are experiencing this issue. Do not run this on your domain controller.

  1. Open an elevated (administrative) command prompt
  2. Run the following commands:
    net stop w32time
    w32tm /unregister
    w32tm /register
    net start w32time
  3. Restart the server (may not be needed, but is a good idea)

After doing this, when running “w32tm /query /configuration” you’ll notice the time source will now reflect “NT5DS”, and the servers should now being using your domain hierarchy time sources (domain controllers).
