I have downloaded 4.0.311.1 to test 5Nine Hyper-V Manager.

I have connected to a Hyper-V server 2012-r2 no-domain; no problem.

A second host Server 2012R2 HV Role, non-domain gives me Error: Wrong Credentials specified to connection to host...

I can connect to this hosts' admin shares without problem. All WMI firewall rules In and OUT are allowed.

Any suggestions?
