Migrating to Windows Server 2008 from 2003 Domain

I started out with a single Windows 2003R2 Server which runs our small network. We decided to buy a new server which has Windows Server 2008 Standard. So I started reading the forums to determine the best way to switch to switch to the new server and eventually take the old system offline... I found and followed the instructions below:

1 -Make sure your current Active Directory Environment is healthy and
functioning right by running a dcdiag /q at the command prompt, look for any errors.
2- Prepare your current environment for W2K8. On you current Windows Server 2003 Domain controller, logon with an account that is a member of the schema Admin, insert the W2K8 disk and run adprep /forestprep and adprep /domainprep. This will upgrade your schema to w2k8 verion 44.
3- Add the new w2k8 machine as a member server to your domain
4- Make the W2K8 a domain controller in your exiting domain by running
dcpromo and follow the prompts, Also recommended to install DNS at this
stage if prmpted to d so, if not then install DNS immediately after DC promo
is complete. After w2k8 have been promoted as a domain controller, wait for
replication to complete, do a dcdiag /q and look for any errors. At this
time, make W2K8 DC to point to itself for DNS
5- Transfer FSMO Roles to W2K8. If no errors, then move all the FSMO roles
from the W2K3 domain controller to the new W2K8 domain controller.
Instructions to do this can be found here:
6- Migrate your DHCP from W2K3 to W2K8.
7- At this time, proceed to demote old w2k3 as a domain controller. ( I
will prefer you do this after about 2 weeks, just to make sure that
everything is working as planned.)

During Step 4 running dcpromo, I got a msg about authoritive dns.. I didn't think much of it as the process completed.. when I run dcdiag I get a bunch of errors.. I am assuming something is messed up in dns.. I attached a txt file with the results... any help would be greatly apprecieated, trying to do as much of this over the weekend as I can...

I had attached a migration guide which might be helpful for you. Try to read the guide below which can provide a better overview of the migration process. You might be missing something out and reading the query it looks more complicated to comment on.
