We recently moved our hosting from Y! to DreamHost where we were using FrontPage 2002 as our main editor. Now that we have moved to DreamHost we can not log into our web site from FrontPage. We can login via FTP just fine. We are not on the FrontPage server since we don't need FrontPage extensions and want to use FTP and CGI.
For what it's worth the login and password are the same on DreamHost as they were on Y!
