I am imaging servers from stock AMI's in amazon. For business purposes I have to briefly join these servers to the domain so that I can install some agents before I shut them down, sysprep them, and image them as our golden images.

When I try to remove these servers from the domain by joining them to a arbitrary workgroup, I am getting an Access Denied error. I am trying to do so by running the following powershell:

Add-Computer -WorkgroupName 'AWS' -Force

I have tried doing this by passing random credentials to it as well. It is making me feel like I need credentials for my current domain, to join it to a workgroup.

However... When I go through the Gui to add it to a workgroup, I receive a credential prompt where I can literally give it Username: 'A' - Password:'A' and it will join just fine. After a reboot, my server is completely off the domain. I am not even logged in with a domain joined account, it is the local administrator.

Any ideas? Thanks!

Might try Remove-Computer

Remove-Computer -LocalCredential $cred -WorkgroupName "Workgroup" -Force

Could throw in a -Restart if you want
