We had exactly the same problems, site on IIS, couldn't implement mod_rewrite 301s etc, we moved it to Apache, reprogrammed the asp stuff, implemented all the necessary 301s and the site came back quite quickly. Obviously, we also made all the urls correct etc before moving the site. This resolved that particular issue, but it's possible we're still seeing some sideaffects of that problem currently, it's hard to say, but I can't help wondering if some of those old pages are still causing us problems.
