Just a quick blog on MDT, in case anyone else has run into this. One thing to keep in mind is that MDT does have a lot of moving parts, and sometimes you need to make changes to your main configuration files. Why? Maybe you've changed a password on a domain account that connects to capture your image, for one example.
So when you ever modify your customsettings.ini or bootstrap.ini, you need to do 2 things:
1. Completely rebuild the Deployment Share in MDT
Yes, that means right click on your deployment share, and "Completely regenerate the boot images"
2. Either A or B
A. (Preferred) Copy your WIM that you just created from step 1 (say from X:\DeploymentShare\Boot\(architecture) to X:\RemoteInstall\Boot\(architecture)\images, then restart Windows Deployment Services
Note that X represents the drive your deployment share is on (assuming it's on the root), and (architecture) is x64 or x86, depending on the boot WIM you created.
B. Go into the WDS console and refresh or add the new boot WIM to the console.
If you indeed need to make a change to those two files, don't forget the extra steps. Hope this helps someone else.
