You can, but you should only do it if absolutely necessary.

Honestly, you'd be better backing up your data, taking notes on the structure and starting over from scratch.

There is a good chance you'll always have weird behavior in the future.

This isn't a simple machine rename, you are going in and changing AD.

Here is a step-by-step guide.

I'd set up a lab and try it there first.

Also, before production, make sure you have backups of everything.

You might also want to get some more categories added.  VB Script is not where this should be.

I'm afraid not. Domain rename is not supported in the Essentials OS line without a full OS reinstall. This is mentioned here:

The server name must be a unique name on your network. You cannot change the server name or the internal domain name after you finish this step.
I believe the installation wizard states the same thing during initial setup.

I disagree that there has been no valid response. When the question is "Can such-and-such be done?" a response of "I'm afraid it can't, and here's an official statement supporting this" is perfectly valid.

Agree with DrDave242.  Sometimes the answer is "no".

Points should go to him as I missed the "Essentials" part of the question.
