I have a Project Web Access site collection that contains at least 100 pages (out of several thousand) where Page Viewer web parts are targeted to a URL that is no longer valid. The URLs have changed from a pattern like http://randomsite101.site.com/whatever to http://randomsite/whatever (don't ask why we don't deal with this by DNS).
I could change the URLs manually if needed but the larger problem is that the target URL for a page viewer is apparently not indexed for search. Any clever ideas for finding these instances?
