Not started RRAS is likely the reason for you to not have the DUN working.
Do you have all the components listed in this thread?

I did test DUN a while ago with XPProEmulation image ( on SP1. I don't think you'd appreciate me posting the
project component list as it is more than 2300 components there. But you can give it a try if you have time.

Btw, what dll could not be loaded?

Also, please check your FBALog to see if there were any errors related to RAS.

PS. Just in case, verify that the "Plug and  Play Sfotware Device Enumerator" and "Local Network Bridge" components are included in
your configuration with all their dependencies resolved.
