I read a lot of artices like this http://timo.dgtl.de/2015/02/scvmm-2012-r2-app-controller-connection-error.html
they all say about cleaning Administrator user role from unresolvable members. But I have no such things and can't find the reason of the problem.
My situation is:
There is a hyper-v cluster in one domain and several standalone hyper-v servers in a trusted domain. VMM server is in the first one, and users in one more trusted domain.
I created a Delegated admins role with maximum scope and permissions and a group of delegated admins with permissions in the group of hosts in trusted domain.
But after that I have a problem with connecting to VMs. For example users that have Delegated admin roles in the first domain cannot connect to VMs on the hosts in the trusted one although they have maximum VMM permissions and runas account there. And trusted domain admins cannot connect to vms on hosts in first domain.
In AppController they get blank screen with two buttons (Alt+Ctrl+del and Reconnect) and in VMM console - error 0x0003 0x0300
I cannot understand why it works this way and cannot find any articles on how the system of VMM permissions works in details. Can anyone help?
