Need help with "No input file specified" error

[tbrothers]

I'm new here so if I posted this incorrectly please go easy.

I recently moved my website from a Unix hosting service to a Windows
2003 IIS hosting service. The site was converted from php/mysql to
asp/mssql.

The search engines still have a lot of links cached that point to
.......php. When a user clicks the link they get a blank page that
reads "No input file specified.". This page does not appear to be a
standard error page.

My question. Is there a way to redirect all ....php page requests to
my home page?

Thanks,
Terry
