Demote windows 2008 r2 core dc

Removing the functionality those services provide involves some planning. You'll also want to be sure that machines with static IP configurations also don't reference these services. Having said all this, you really should have at least two DCs at all times.

Don't migrate to a configuration with a single DC. Microsofts technet has a whole chapter on this. One would assume they know the 'right' way of doing this. However, if you are not sure of what and how to do this, then consider that you are messing with the core functionality of your network. Tread carefully. Double and triple check. Or hire someone to do this for you. Yes, that MS guide is the "correct" way to do it.

Oh, and make sure you have a functional backup of your domain first. It's pretty easy, honestly, and I could do it in my sleep as could anyone with a lot of AD experience , but you want someone around who knows about AD in the event something goes wrong.

Now, a bit of advice that's more useful than how to do demote a DC It's a very bad idea to only have one which it sounds like what would happen if you demoted it. Having a second around provides redundancy and allows you to actually do things on your DCs patches come to mind without having downtime. Also, why do you want to demote this at all?

In general, as a sysadmin, you shouldn't be making changes for no reason. If there isn't a good reason to do something, don't do it. Why do you want to demote this DC, and what do you think you'll gain from doing it? I'd bet that even if this goes off smooth as silk, you'll be putting yourself in worse position than if you hadn't done it all, which should be plenty of reason to reconsider this action.

One of the action plans suggests to power off the domain controllers for 1 or 2 weeks to remediate any dependencies after impact analysis and then demote and decommission the server eventually.

Based on your experience, do you see any issues with powering off dc's for 2 weeks? We won't remove the SRV records until they are decommissioned but powering the dc's off will create any slowness in authentication or something?

Please suggest if there are any precautions or steps to take care before we commence the decommission. Attachments: Up to 10 attachments including images can be used with a maximum of 3. Hi, Just want to confirm the current situations.

If there's anything you'd like to know, don't hesitate to ask. Shouldn't be a problem to do this. In the end if the demotion is problematic you can remove from network then easily perform cleanup to remove them. Before doing any critical changes in domain, remember to back up the DCs.
