Ari, thanks for your help with this.... The only links to the pdf files are at the bottom of this page: http://www.dummycomponents.com/catalog.htm All pdf files reside in this directory: http://www.dummycomponents.com/pdf/ > Can you provide hyperlinks to the pages in question > so we can view this error? The only problem from a browser point-of-view with pdf files is that the original NS 6.0 release wouldn't do pdf files. I don't know if that has anything to do with this 404 error or not. Many thanks, Pat pmeeks at msn.com
