I set up an Active Directory (AD) Domain Controller on a Windows 2003 server. I let the wizard do all the work.

I can login with the domain users I made. However, when I go to add a computer to the domain I get the incredibly helpful error:

The parameter is incorrect

Any ideas?

From the NetSetup.log:

Are there any additional logs in the system event log? – EEAA Sep 25 '10 at 0:52
Not really. On the server There is a Directory Service node. There is a ton of info entries there. But no errors or warnings. Client side... Nothing. – NitroxDM Sep 25 '10 at 3:33
I don't know if matters... this is the Enterprise edition. – NitroxDM Sep 25 '10 at 3:35
that is a strange error, did you let the wizard create the dns servers for you also? from the workstation does the dns info make sense? – tony roth Sep 25 '10 at 4:10
what's on the workstation's netsetup.log? – natxo asenjo Sep 25 '10 at 8:36

As discussed in the comments, the problem was that the machine in question had a mapped drive with the domain controller.

error 1219 in the netsetup.log is according to msdn "ERROR_SESSION_CREDENTIAL_CONFLICT 1219 (0x4C3); Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again."

Try dcdiag and netdiag from Support tools. Ensure that the computer uses DC DNS server. Check this DNS for access with nslookup against the DC records.
