File associations not responding in Vista Home Premium

I can not associate htm and html files to Front Page 2003. When I try to
Open With, point through the files to find FP03 program file, it will not
associate with html or htm. It instead changes to an Internet Explorer
file. It is strange. I think I need to set all associations back to default
for programs and start over. Is there a way to do that? Is there a
Microsoft utility to manage associations. I know how to associate with Open
With and start, default programs in Vista. It just will not correct the
problem.

It appears that what looks like the Front Page 2003 program icon is not
connected to the right program.
