DC Upgrade 2003 to 2008 r2 DCDIAG issues

While working to upgrade out of a Svr2003 network, the first 2008r2 DC has been put online.

The 2003 FSMO DC went through the /forestprep and /domainprep with zero issues and the domain is at 2003 function level. All FSMO roles have been transferred to the new 2008r2 DC (AD-PDC). While working on the upcoming changes for the last 2003 DC to be dcpromo'ed I noticed a lack of connection (netlogin) in Exchange that led to looking into DC functions via DCDIAG.

Attached is a log of the DCDIAG /E test

It has been suggested that I open this new question here to try and find the best result.

I tried to re-run the /forestprep and /domainprep on the 2003 box - both returned nothing to be done...So, what is the best next step?
