Windows Domain Name Change

Hey Experts,

I have just setup a .local domain recently with 2 AD servers and while I have done quite a bit of work on the domain I have yet to add any users to the new domain.  I want to eventually setup a magic triangle so I have read about the issues that plague a .local domain with the Mac setup.  So for that reason I want to change from .local to .private.

I have tested changing the domain name in VMs using rendom and am not happy with the results as I have seen errors and what not and I would rather start with a fresh AD given the stage that I am in.

My question is this, can I simply remove AD services as a role from the AD servers and then re-setup AD services with my new .private domain?  If so, is there a chance that this would leave any data behind of the old domain?

If not, I assume I am looking at a full wipe / reinstall for my 2 AD servers...?

Thanks for any help you can give!

If you don't found to change domain name. Then just uninstall Active directory service using command dcpromo then reinstall the your new AD with new domain.

Hey sushil84,

Thanks for the reply!  Does removing AD services through dcpromo completely uninstall all the AD files?  I just want to make sure I am not going to have issues down the road because of some files left behind.

Thanks

if you run dcpromo for remove Ad  and you have not got an error then all ad related files will be removed from the server.

If you get an error then you have to perform the  dcpromo /force and also perform metadata cleanup to removed AD related files from the server.

To perform metadata clean refer below link.

Hey sushil84,

Thanks again for the reply.  One last question.  Is there any reason to think that if all goes well with the AD removal and then reinstall of the AD with the new .private name that I would have any problems from renaming the domain in the future?

I don't want to have to start from scratch by wiping the servers but if that would be the best thing to do then this is the time to do it.  If it won't really make a difference from the AD stand point then I would likely choose to just remove / reinstall the AD services.

Thanks again for all the good info!

No there is no problem to rename domain name in future but in your environment other services mean exchange certificate authority running sometime you will facing issue on the server exchange and other.

Hey sushil84,

Thanks again.  I have no plans to rename the domain in the future.  I just didn't want to go through this process and in 3 months see that there was something left behind from the .local domain that will cause a problem for the new .private domain that I change to.  From what you are saying it doesn't sound like that should be an issue.

Thanks!
