Search Engine Safe (ses) URLs

I am running a test server with MX7 and IIS5. I have SES urls working on a production server with MX6.1 but this test server will not go past the home page. Every link I click loads the home page. I have followed the directions for uncommenting lines in the web.xml file (they were already uncommented) and made sure the "see if file exists" option is unchecked in IIS. Still no luck.

Any ideas?
