Redirect from domainname.com to www.domainname.com

[okiiyama]

I have an ssl certifcate for example:

http://www.domainname.com.

Its not a wildcard certificate, so when a user types in just domainname.com, a certificate error happens.

Can I redirect to

http://www.domainname.com,

using IIS or do I need to modify/add a dns record?

How would I do this.

Thanks

i solved it myself, as what usually happens 5 minutes after posting a question.

In IIS under the home directory tab of the site, I selected URL Redirection.
