My site responds to both domain.com and www.domain .com.  To resolve this issue, I assume that all I need to do is remove the domain.com alias?  But before I do this, I wanted some confirmation that I am thinking correctly.  Thanks!

Thanks.  Worked Perfectly.  I use powerdnn.com as my hosting provider and I simply had to change a page with some code to get this accomplished.  I am running DNN 5.4 and needed to modify the page /SiteHeader.aspx.  I simply added this code and the redirect now works.  (I believe that this change is host provider specific.)

<script runat="server" language="VB">
    Private Sub CUSTOM_PageLoad_ForceWWW(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim RequestURI = Request.Url
       
        If Not RequestURI.Host.ToLower().StartsWith("www.") Then
            Dim NewURL = RequestURI.Scheme + "://www." + RequestURI.Host + Request.RawUrl
           
            Response.Status = "301 Moved Permanently"
            Response.AddHeader("Location", NewURL)

        End If
    End Sub
</script>
