Question : Replace a primary domain controller procedure question

Hello.
I have a Windows 2003 domain with one domain controller.
Recently I installed a second domain controller. I transfered all five FSMO roles to the new domain controller and I also checked the "Global Catalog" check box.
It seems to me that there is nothing else required for the new server to become the primary domain controller in order to discard the old one.
Although,when I turn the old domain controller off, name authentication and domain services stop working on the network.
I really need to discard the old server and make sure that the new one becomes the domain controller. What should I do next?
Thanks in advance.
