All content that is crawled requires the use of a protocol handler to gain access to that content. Office SharePoint Server 2007 provides protocol handlers for all common Internet protocols. However, if you want to crawl content that requires a protocol handler that is not installed with Office SharePoint Server 2007, you must install the third-party or custom protocol handler before you can crawl that content.
The following table shows the protocol handlers that are installed by default.
Business Data Catalog
