Exploit Guard - Network Protection
I've just found out why it no longer works on my Windows 10 Pro machines, it's now a Windows 10 Enterprise only feature: https://docs.microsoft.com/en-us/windows/security/threat-protection/windows-defender-exploit-guard/troubleshoot-np
I've just tested it on Pro 1803 (17134.1) and it works, notifications and blocking.
We have a few PCs, pre and post 1709, that Defender is completely cutting off the network. In one case deleting wdnsfltr.exe and .sys solved it. Nothing in the Defender Event logs about blocking access to the network or a bad site. We are deploying via Group Policy from Server 2016. Win10 Pro clients.

What platform versions are the affected clients running?
Win 10 Pro.
One was 1709 and the other was 1603.
In the case of 1709, we had to delete wdnsfltr while unjoined.
In the case of 1603, we took it off the domain, applied 1709, rejoined and network came back. wdnsfltr never started up in this case.
