We've managed to add 2 DB servers at a local site (both running
Win 2012 DC) into a cluster.
Now, when trying to add a 3rd node (over the WAN) into the
cluster, it gave the attached errors.
We've permitted the firewall rules as per MS recommendation.
When did we go wrong & how to fix this?
We plan to set up SQL2012 AAG (AlwaysOn Avail Grp)
