Changing Domain Names on AD

Hello all,
I have a client that has a domain of (for instance) xyz.com for their internal Active Directory.  It was setup wrong and should be xyz.local from what I understand.
To fix this on the server (it is only one server in one location and they are running DNS but not DHCP on the server) would I remove Active Directory, then reinstall it with xyz.local or is there some nice program that will change everything in AD from xyz.com to xyz.local?

Then on the PCs, they will be trying to log into the xyz.com, I know that you unjoin the domain then rejoin the new domain.  This will create a new user on the PC.  What is the best way to copy everything over from one user id to the new user id (including Outlook (and they are using POP accounts))?  I don't want to have to resetup Outlook for every computer user.

One very last question.  If down the road this client that has xyz.local as their domain decides to install an Exchange server and get their emails through the Exchange server, do we have to change their domain again to whatever the email domain is or can we leave it and just let Exchange do its thing?

Thanks,
Kelly W.

Thank you for the answer to my third question.  What about the first two questions?
Thanks,

1. as i said, you use domain name change software that provided that will change everythign in AD from xyz.com to xyz.local without reinstalling.

2. and if you unjoin and rejoin domain, then you need to repoint it..
there is unsupported way like

if not, you will have to migrate one by one, which always be painful as usual like you say.

Hello,
Okay going through all of these steps from the first link, when setting up a Control Station (now remember we have only ONE file server and it is the domain controller) it statest that you cannot use a domain controller as a control stations to run rendom from.
So what is a place with only one server that is a domain controller supposed to do?
Thanks,

Actually this has taken a different turn.
The whole reason of changing the domain from xyz.com to xyz.local is because of two things:
1)  Emails - cannot get to xyz.com from the inside (POP3 accounts hosted on the outside world)
2)  Website - xyz.com is hosted the same place the emails are and cannot get to that from the outside world.

So I fixed #1 by adding an A record to the DNS of mail.xyz.com with the IP address and that works.
How do I fix #2 so that they can get to xyz.com website?
Thanks,

That seemed to work when we had to do it.
