There aren't many of still using OS 9 any more, so . . . don't really have recent experience with your problem, and am not sure exactly what the problem is. Sounds like you try a search, but no results show in the results columns.

Just a guess: Take a look at your connection tab (if not turned on, I think it's in the View menu), and look at the vendor/version column.

By disconnectiiong and reconnecting from the file menu, you should get a different set of hosts. Maybe the new hosts will return results.
