DVD Share on Vista Home Premium Failing

"UPDATE:
- I can't find any Local Policy Editor for Vista Home Premium, as suggested.
- I did learn about registry keys: allocatecdroms, allocatefloppies, allocatedasd and tried adding these keys (individually and collectively) and setting them to both 0 or 1. There was no positive affect on read access to the DVD root folder - always Access Denied."
