I have solved my problem - here are the details....
Because of another post where the user said it depends on the version of Windows 2003 Disc that you have installed I tried the following...
I tried the IDR wizard again using new discs of Server 2003 Standard Edition, 2003 Enterprise Edition Pre SP1, and 2003 Enterprise Edition with SP1. All three discs allowed me to complete the IDR Wizard.
I then went back to the original disc I had been using and the errors came back. I checked and it was Enterprise Edition Pre SP1, but it must have been a bad copy or a bad version. (original discs in the vault - I was working with copies).
So - if you're having this error - and you're at Version 9.1 with SP3 and have the following patch installed...

....then you might want to try with a different disc.
Good Luck!
