Been stuck at the coal face trying to figure this one out for best part of 24 hours now.
I have a dell blade server, and 3 of the nodes on it are configured as Windows Hyper-V 2012 core servers, with a verity of VM's running on them.
A week ago, after a disk crash on my workstation, I had to re-install windows 10 enterprise. As it was a re-install I patched it all the way up to 1809 (Prior to the crash I was at 1803).
After I reinstalled, I went to access the Hyper-V servers as I had done without problems previously, with both Windows 7 and W10-1803.
As expected, I got the various winRM trusted hosts errors, so I ran the required WinRM commands, made sure the firewall had the correct rules in place, etc etc...
However, I cannot in any way connect to my servers using Hyper-V.
On the advice of some other technet forums, and various MS-Connect posts and MSDN Blogs, I installed the "Windows Server Manager" on the windows 10 machine, and that also has problems accessing the Hyper-V servers.
Remote desktop connections work totally fine, I can RDP into the servers no problem. All 3 servers have both an Administrator account on, and an account using my own Login Name that I log onto my Windows 10 PC with, which is also part of the administrators group on my machine, and on the 3 remotes.
All the machines are in a work group, rather than in a domain, but the work group settings appear fine too, as I can access the file shares and other resources perfectly fine, from my personal account, and logged in as "Administrator"
I've disabled the firewalls on the 3 Hyper-V servers and that's made no difference (Although not tried disabling the Win10 FW yet)
Corefig, which I have installed on each of the Hyper-V servers tells me that all the various rules are enabled, and that WinRM is correctly set up, I have the security level set to allow "All Clients", not just the newer more secure ones.
I cannot see anything that appears to be wrong.
The windows event logs don't give me any useful information, other than the updates I last tried to install failed (When in actual fact according to the screen I was looking at, said they had succeeded).
In Hyper-V manager, all I get is this:
Where "Lucinda" is the Windows 10 machine used for management, and "CB*" are the 3 hyper-v nodes.
In server manager, all I see is this:
I'm really out of options now. It all worked perfectly previously, under 1803, but now it doesn't matter what I try I can't seem to get it to work.
I'd really appreciate any thoughts anyone has.
Cheers
