Upgrading Server 2000 to 2003, in a Domain that has 2003 servers running AD in 2000 native

This seems confusing and I can't figure out the logic behind why the previous Admins did this.  I'm one of the admins that is running a mixed server 2003 and 2000 network.  Active directory on the 2003 Domain Controllers is running in 2000 native mode.

I've run adprep /forestprep from the schema master and get this message
"Forest-wide information has already been updated"

when I try to run adprep /domainprep I'm told
Domain-wide information has already been updated.

So I go back to the computer I'm trying to promote to a domain controller and run dcpromo I get the message window

"The operation failed because:

The Active Directory Installation Wizard cannont continue because the forest is not prepared for installing Windows Server 2003.  Use the Adprep Command-line tool to prepare botht the forest and the domain.  For more information about using the Adprep, see Active Directory help.

"The version of the Active Directory Schema of the source forest is not compatible with the version of Active Directory on this computer.""

Which is where I'm lost, because I Ran Adprep, and it did nothing.  

Any Guidence is very appreciated.

1) check to make sure the forestprep and domainprep are being run from Windows 2003 disks and not Windows 2000.

2) Also if the Windows 2003 machines are Windows 2003 R2, you must run these commands using the R2 CD (second Cd rom)

Actually I have a question, will adprep /forestprep and /domainprep change anything on the server?  I guess I'm just worried about breaking something.  Is there anything else I need to know about running this?

Hi Xaosob1,

just an additional note

if you are runing the R2 schema update as mentioned above, you also have to run the adprep /gpprep switch in addition to the domainprep and forestprep switches

its run from \CMPNENTS\R2\ADPREP   on the second cd

Sorry things got Crazy yesterday, I was unable to take care of this.  I'm going to attempt this after 5pm (AZtime) today.  First I need to talk to my boss and make sure there has been a full backup of the domain.  Thanks for all the help!

We decided to hold of and research a bit more.  We're uneasy about playing with the schema and thing instead of switching servers, just to finish the 2000 to 2003 upgrade on the existing servers for now.
