Rather than reinventing the wheel, I will say this.  You need to use your 2008 disk to run, from a DC, the adprep /forestprep and /domainprep.   It is different for R2. Your 2003 is most likely 32 bit, so you will use adprep32 instead of adprep if that is the case.  For detailed, step by step instructions, check out this article:

Once the domain is prepped, simply use the Add Roles wizard to make your server a DC/DNS server.

1 you will require to run adprep /forestprep  with the 2008 cd.
2 on the new 2008 you will require to install AD DS role.
3. DCPROMO the new server to become the member of the existing domain.
