ColdFusion 9 issues with SBS Sharepoint and other sites.

I had helped someone install CF9 on their web server and we choose all sites when asked what IIS sites to connect it to. They had several IIS sites for their MS Small Business Server and one CF site. The CF site worked and we called it a day. A few days later they contacted me saying the SBS Sharepoint and other sites where breaking and the MS tech support thought it was ColdFusion. Well I had not heard of this before but went out to help. It seems that the CF 9 install adds a wild card IIS handler mapping for "*" so all requests go through CF. When they turned of the CF application service images were broken until they removed the wild card mapping. Why CF 9 needs a wildcard mapping I do not know.
