I been working on a my Dafting deployemtn for a week now. Im building a base image using MDT2010 and using the copyprofile setting recommend by MS to make sure the files are being move to the default profile so other account can use those settings.. None of the settings in Autodesk are sticking. IE. Splash screens, removal of exchange connections. The major problem here is the reinstall of the English Lang Pack, and first time startup time happens every time. This proccess slow down application startup and valued class time.
Any help would be awarded with Pats on the Backs.
Please check this article on the normal behaviour of Autocad on first run.

If you are missing any of registry/folders it would start the secondary installer
Keep in mind that roaming profiles is not a supported platform for Autodesk products. Profile information must reside on the local hard drive and the user should have local admin rights initially during first startup.
