Hi Bobby

You can add these settings to you web.config:

<system.web>
   <authentication mode="Forms">
       <forms loginUrl="Login.aspx" />
   </authentication>
</system.web>

<location path="Admin.aspx">
   <system.web>
       <authorization>
           <deny users="?"/>
       </authorization>
   </system.web>
</location>

If you need different settings for other files then you can add more
<location> settings.

It's also possible to do the same thing using code, with something
like:

If Not User.IsInRole("Administrators") Then
   Response.Redirect("Login.aspx")
End If
