Can't promote new 2013 Windows server to Domain Controller on 2003 domain

I have a Windows 2012 server that I am trying to add to an existing 2003 domain. When I started this, the domain was at the 2000 level. I have raised the level to 2003.
When I am in the server manager on the 2012 machine, it still thinks it is at the 2000 level because it will not allow me to get past the first step of joining the server to the domain. I get the error "Verification of replica failed. The forest functional level is Windows 2000...."
I have confirmed that I am at the 2003 level and rebooted both machines. Is there another place I need to change?

You might have changed the domain functional level and not the forest functional level.


Please raise the FOREST functional level.
To raise the forest functional level

    Open Active Directory Domains and Trusts.

    In the console tree, right-click the Active Directory Domains and Trusts node, and then click Raise Forest Functional Level.

    In Select an available forest functional level, click Windows Server 2003, and then click Raise.
