Indexing network volumes with Spotlight

Now that I have Tiger installed, I wanted to make Spotlight index the SMB volumes on my Windows Server 2003 file servers. Nope; there’s no way in the user interface to tell Tiger what you want it to index. You can exclude certain items (and it looks like you should, at a minimum, exclude the Microsoft User Data folder to keep Spotlight from hammering your Entourage database), but you can’t add items… unless you use the command line. Google was useless, but a quick Feedster query turned up these instructions, which I’m now testing (the key is to use the mdutil command to enable the volume for indexing).

Update: these instructions turn on indexing, but no results are ever returned. Ooops.
