Indexing a file share required a MOSS server and it is quite easy to set up. Go to your Shared Services Provider -> Search Administration -> Content Sources. Create a new content source, choose file share and enter the path to the file share. You then need to perform a full crawl. Also make sure that your default content access account (specified on the main search admin page) has read permissions granted on your file share. For more details, see my post on
how to index a file share.
