I have two identical Windows Server 2012 R2 DHCP servers in a load balancing/failover configuration. The SAM server is on the same subnet on Windows Server 2016. One of the application monitors I have assigned is the DHCP user experience test. On one of the servers, it tests just fine. On the other, it always times out and is stuck in an "unknown" state. I have confirmed that the DHCP service is not only functional but reachable from the SAM polling server. Any ideas? I have tried the basics like rebooting both servers and remove/re-add the node.
