For anyone looking for a UI option using IIS Manager.

Open the Website in IIS Manager
Go To Request Filtering and open the Request Filtering Window.
Go to Verbs Tab and Add HTTP Verbs to "Allow Verb..." or "Deny Verb...". This allow to add the HTTP Verbs in the "Deny Verb.." Collection.

This worked for me but only after forcing the specific verbs to be handled by the default handler    lt system web gt         lt httpHandlers gt              lt add path     verb  OPTIONS  type  System Web DefaultHttpHandler  validate  true   gt       lt add path     verb  TRACE  type  System Web DefaultHttpHandler  validate  true   gt       lt add path     verb  HEAD  type  System Web DefaultHttpHandler  validate  true   gt    You still use the same configuration as you have above  but also force the verbs to be handled with the default handler and validated  Source  http   forums asp net t 1311323 aspx  An easy way to test is just to deny GET and see if your site loads

This one disables all bogus verbs and only allows GET and POST   lt system webServer gt     lt security gt       lt requestFiltering gt         lt verbs allowUnlisted  false  gt       lt clear  gt       lt add verb  GET  allowed  true   gt       lt add verb  POST  allowed  true   gt         lt  verbs gt       lt  requestFiltering gt     lt  security gt   lt  system webServer gt
