RSAT missing DNS Server Tools?

[UPDATE] The final 1803 release of RSAT is now on the public RSAT download page. Look for the WS_1803 package there, thanks!

Here's the official KB workaround published by the DNS team:

https://support.microsoft.com/en-us/help/4055558/rsat-missing-dns-server-tool-in-windows-10-version-1709 (thanks Christoff MOrlOck for posting this previously)

The RSAT download page now also has this info under Additional Information:

Issue: DNS Tools missing
Impact: WS_1709 RSAT package users
Resolution: Use the WS2016 RSAT package or apply this workaround

The DNS team has also fixed the root cause for RS4 and so the workaround will not be required for the upcoming RS4 RSAT package update.
