Windows 2016 cluster validation test fails - Why isn't my server listening on UDP Port 3343

id flag

Getting a failure message similar to this

Network interfaces s-test-01.assemblyni.gov.uk - LOM1Port1_Mgmt and s-test-02.assemblyni.gov.uk - LOM1Port 1_Mgmt are on the same cluster network, yet address 10.63.35.30 is not reachable from 10.63.35.31 using UDP on port 3343.

A "netstat -a -p udp" shows that both servers are not listening on Port 3343

Since the servers themselves are not listening on this UDP port, then it can't be a firewall or network problem, correct?

Thanks for help

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
