The Netcraft Web Server Survey is a survey of Web Server software usage on Internet connected computers. We collect and collate as many hostnames providing an http service as we can find, and systematically poll each one with an HTTP request for the server name.
In the November 2002 survey we received responses from 35,686,907 sites.
Approximately 8% of Microsoft-IIS sites tested in 2001 had RDS open to the public; in 2002 this has fallen to around 5%. This fall can be largely explained by the gradual migration of sites to Microsoft-IIS/5.0, where RDS is not enabled by default. Almost no Microsoft-IIS/5.0 sites we have tested were offering RDS and the proportion of Microsoft-IIS/4.0 sites offering RDS is fairly stable at around one in four.
