IIS (Internet Information Server) is a web service component, including Web servers, FTP servers, NNTP servers, and SMTP servers, it is used for Webpage Browsing, file transmission, news services, and email sending. It makes it easy to publish information on the Internet (including the Internet and Local Area Network.

When a service of IIS is installed (Web, FTP, SMTP, or NNTP), a default site is configured for that service. IIS creates all the necessary metabase paths and locations, and sets the appropriate properties for that site. possible values to which IIS might set a property are listed in this section of the metabase Property Reference pages. if an internal default is "not specified", that is because IIS setup does not have a default l
PS: This brute-force password cracking tool is quite powerful and supports online password cracking for almost all protocols. The key to cracking the password is whether the dictionary is powerful enough. Social engineering penetration can sometimes get twice the result with half the effort. This article only explores the test from the security point of view, and uses the content of this article to do the damage, it has nothing to do with me.
