redirecting http://domain.com to htttp://www.domain.com in IIS

my site currently isn't working if I only type http://domain.com in the browser instead of www.domain.com. I was thinking about redirecting the domain.com to www.domain.com in IIS but somehow it isn't working correctly.

I开发者_JAVA百科 get this error message in the browser:

Hostname lookup for "domain name" failed

What am i doing wrong?

create a new web site for the subdomain using the IIS Manager, and add the www sub-domain (e.g. www.domain.com) as a new host header value listening to the same IP address as specified in the DNS entry. The port is set to 80 (the default for http requests). The host header can be added by clicking on the advanced tab next to the IP address configuration for that web site application. Set the home directory for the www subdomain web site to the same directory. For example, if the domain.com points to C:\Inetpub\wwwroot\ and the www subdomain needs to be setup for C:\Inetpub\wwwroot\

There are some chances you need to configure your dns too. this depends on how your dns provider is, please their help site or support.
