You need a url rewriter such as IIS mod-rewrite which enables .htaccess on IIS. You can use rules like below to do 301 redirects

RewriteEngine On
RewriteRule ^old_page\.html$ /new_page.html [R=301,L]

But I guess you are on a shared hosting, so installing such a tool may not be an easy procedure.

Unfortunatelly, using meta refresh is not a 301 redirect and you have no SEO benefit
