Dunno about .NET, but can you change IIS to use a different root folder, which only has unavaileble.aspx in it - and make that the default DOC?

If not, I'd suggest adding a <appSettings> to your Web.config so that you can have a "maintenence" parameter. Then, in the base class that all of your pages inherit from, test for that parameter and send the user to the proper page as needed.

protected void Application_BeginRequest(Object sender, EventArgs e)
{
	if (System.Configuration.ConfigurationSettings.AppSettings["MaintenanceMode"] == "true")
	{
		if (Request.ApplicationPath + "/" + System.Configuration.ConfigurationSettings.AppSettings["MaintenancePage"] != Request.Path)
		{
			Response.Redirect(System.Configuration.ConfigurationSettings.AppSettings["MaintenancePage"]);
		}
	}
}

<appSettings>
	<add key="MaintenanceMode" value="true" />
	<add key="MaintenancePage" value="unavailable.aspx" />
</appSettings>    

        Private Sub PortalPage_Load(ByVal sender As Object, ByVal e As EventArgs)

            Response.Redirect("unavailable.aspx")
            'if this works i'll put here the code for read the web.config

            If Context.User.Identity.IsAuthenticated Then
                If Not (TypeOf context.User Is SitePrincipal) Then
                    Dim newUser As New SitePrincipal(Context.User.Identity.Name)
                    Context.User = newUser
                End If
            End If
        End Sub
