IIS 6 WWW in subdomain doesn't redirect

Question

In IIS, I have a subdomain: sub.mydomain.com

BUT, if someone incorrectly types it as: www.sub.mydomain.com it doesn't work.

How do I resolve this issue?

Thanks!

With IIS6 you cannot create wildcard subdomains, you will have to use DNS (or ISAPI rewrite) to handle *.sub.mydomain.com.

For more information on wildcard subdomains and windows you can actually use ServerFault ;-). See this post here: Wildcard DNS and subdomains

For more information on ISAPI rewrite you can use the following page: Creating Dynamic Subdomains in IIS using ISAPI_Rewrite
