It can be done in IIS 6 as well / without using web.config, but instead using the management GUI to add a MIME type for extension . here:

For instance, to serve a .well-known/acme-challenge token, create a virtual directory called .well-known, and have it take its contents from a physical directory (that cannot have names with leading dots in windows). Then add a text/plain MIME type for the extension . in this directory, and you can manually acquire new letsencrypt certificates for a domain that is currently served by an old IIS.
