Remote manage a Hyper-V server from a different domain


You can however remove it from its current domain:

netdom remove /d:DomainThatNoLongerExist.COM HYPERVComputerName /FORCE

Then add it in server manager, right click on it and select Manage As… and you can enter the local admin credentials for the Hyper-V box

Still not entirely sure if you need to run this on the management server…

Set-Item WSMan:\localhost\Client\TrustedHosts -Value -Concatenate
