I have had this issue as well. I have given both my Mac and PC server fixed ip addresses and then it's possible to connect to the server via those addresses! Fill out the instance name - remember uppercase matters! - and then connect.
Thanks so much, Stig. That worked, at least it did using the non-DNS IPv4 address shown in my network properties. Not sure how to assign a fixed address to VEP, nor which one to assign, but what I did worked.
That is at least a workaround.
Again, much thanks.
