Remove a 2003 domain controller from a forst?

At this point, I really just want to get rid of the 2003 DC.  Currently my question is how to remove it from the 2008 R2 DC DNS servers.  When I look in DNS on the 2008 R2 server, I can see the 2003 server in multiple locations as I move down the DNS thread.  Can I just remove the old server as a DNS server?  Will it populate the correct information (or properly remove it) down the thread?

My Windows 2008 R2 server is also listed as a DNS server.

If exchange is installed on the 2003 domain controller? Then you need to first uninstall exchange and then demote the 2003 domain controller to a member server.

How about the DNS question. Is it easy to remove my old server as a DNS server.  Will my 2008 R2 server information be populated throughout the DNS settings?

DNS is integrated with Active Directory. This is why you need to demote the Domain Controller to also remove DNS.

The server I want to remove seems to be the current Primary Domain Controller.  On that Windows 2003 PDC, if I run DCPromo to remove active directory, I am warned about accounts band data being deleted!  Do I need to remove AC from the 2003 DC?  Active Directory is running on the 2008 R2 DC.

Sorry, but I need to get this done as I am constantly getting errors where users need to reboot to gain access to mapped drives on the 2008 server.

I would like to think this is an easy process, but everything points to possible disaster!  Obviously, I am not a pro at this.

Also, on the 2003 server under AD Operations Masters, it shows itself as the Operations Master.  On the 2008 R2 server under Operations Master, it show 'ERROR' The current operations master is offline.  The role cannot be transferred'.  There is a change button here.  Do I want to transfer the Operations Master Role to the 2008 R2 server?
