Recently I experienced something interesting on my virtual machines in my lab and would like to know how this has evolved in recent years.
- 2 domain controllers (Windows Server 2016) virtual machines
- Windows 10 (Enterprise) virtual machines
- 1 "file server (Windows Server 2012R2) virtual machine
Setup was used to test SMB-signing between Windows 10 and the 2012 Server; and to check if an upgrade to 2019 (forest-wide) can diminish the need for SMB-policies and get a more secure environment as a whole.
However, in booting up a wrong VM (don't ask), I was able to replace the gateway IP with a rogue IP. Result, Windows 10 was no longer able to find the file server. After some research, IRDP is one of the protocols that can cause/resolve this.
The last time Microsoft talked about is (roughly) around the Vista-era and its associated kernels in the family.
My question, however basic: what is the current advice from Microsoft to https://admx.help/?Category=security-compliance-toolkit&Policy=Microsoft.Policies.MSS::Pol_MSS_PerformRouterDiscovery on operating systems "after" Server 2016?
