Agent86oz,
Let me check with the OneNote team and see if I can get more information. I know that OneNote developed a specific IFilter to work with the search features in Vista and I'll have to see if development on that IFilter differs between 32 and 64 bit.

Sorry to hear that. The Vista Release Candidate should include the search updates that were in WDS 3.0b2. In addition, we are hoping to release a UNC protocol handler for 3.0beta 2 in the very near future. If you run 3.0 b2 on XP64 and wait on the new protocol handler you should be able to get all of the functionality you are looking for. It may take a tad longer to iron out some of the issues in Vista.
