Unjoining Hyper-V server From Domain

Problem : I tried to remove the hyper-V host from the domain which is not there any more in my lab environment , but it fails with the error " The specified domain either does not exist or could not be contacted ".

Usual way of removing a Hyper-V server from domain :

Login into the Hyperv console and press option 1

Provided the password and username to remove . But it fails stating that it is not able to contact the domain.

Solution:

we need to remove the domain from that server forcefully , used the below command for that

Netdom remove /d:olddomainname.com hypervservername /Force
