Change Name of Server Running Windows Server 2022

Question

Greetings and salutations fellow posters. My company recently upgraded one of our servers to the Core version of Windows Server 2022 and we have been unable to change its name in HyperV Manager. For whatever reason, the server appears with the domain name attached in HyperV Manager despite it not having the domain name on the server itself. It is attached to the domain, and we believe the name became attached because of Server 2022 itself. For example, our servers are labelled as follows:

1. HYPV01-XXX
2. HYPV02-XXX

The one that needs its name changed is listed as:

1. HYPV08-XXX.DOMAINNAME.PRI

We simply need to remove the "DOMAINNAME.PRI" portion from the name of the server, but we cannot find a way of doing so. Any insight on this issue is greatly appreciated.

Thank you,

It appears to be some setup configuration on the new one to where the Select Computer browse dialog does not find the host name but instead only returns the FQDN which is how you see it listed in Hyper-V manager.

Some ideas here with that one

I don't think that's it exactly. This appears to be a DNS (or configuration) problem where this particular host wasn't able to be found by host name when you browsed to add it (Connect to Server dialog) but instead found only the FQDN and so hyper-v manager is happily using that name.
