how to convert httpd.ini to web.config

Hi, I have a website running on the old iis and works fine. But when put on the new server it does not work because of the re-write rules and i believe the new iis does not use the http.ini files.

# Block external access to the httpd.ini and httpd.parse.errors files
RewriteRule /httpd(?:\.ini|\.parse\.errors).* / [F,I,O]

# Block external access to the Helper ISAPI Extension
RewriteRule .*\.isrwhlp / [F,I,O]


#Simple rules
