On the Operations page, in the Global Configuration section, click Site directory links scan.
On the Site Directory Links Scan page, in the Choose views to scan section, type the URLs of the site directory views that you want to scan for broken links in the Site directory view URLs box (for example, type http://[ServerName]/sitedirectory/lists/sites/allitems.aspx).
