Hi @Trent Helms - MSFT ,
thanks for your time in this case.
The problem with the VLAN was real...fixed this with set in in PoSh to VLAN 1 and after that back to VLAN 0.
Now its editable...crazy.
But, get another error after the point "checking cluster".
Must I change something in WinRM on the HCI Servers?
Thanks
