asp.net security : Forms Authentication with Active Directory

I have a number of remote users that connect to the domain through a VPN
device. I need a simple process for them to be able to change their passwords
- some of them only have http bookmarks. The VPN is configured to
authenticate users with the Active Directory.
I found this article: http://msdn2.microsoft.com/en-us/library/ms998360.aspx
& followed along - I can do a little hacking, but I'm primarily a system/db
admin.

I can run the web page in the designer & it works fine, however, when I
attempt to run it on the server, from another server in the domain, or from a
bookmark on the VPN, I get an web.config configuration error, & the following
line is highlighted:

<authentication mode="Forms">

I don't understand what's wrong. Is the web.config file case sensitive? Do
the entries need to be in a specific order?

If it will help, here is my entire web.config:
<?xml version="1.0"?>
<!--
Note: As an alternative to hand editing this file you can use the
web admin tool to configure settings for your application. Use
the Website->Asp.Net Configuration option in Visual Studio.
A full list of settings and comments can be found in
machine.config.comments usually located in
\Windows\Microsoft.Net\Framework\v2.x\Config
-->
<configuration>
<appSettings/>
<connectionStrings>
<add
connectionString="LDAP://MyDomain.local/CN=Users,DC=MyDomain,DC=local"
name="ADConnectionString"/>
</connectionStrings>
<system.web>
<!--
Set compilation debug="true" to insert debugging
symbols into the compiled page. Because this
affects performance, set this value to true only
during development.
-->
<compilation debug="true"/>
<!--
The <authentication> section enables configuration
of the security authentication mode used by
ASP.NET to identify an incoming user.
-->
<authentication mode="Forms">
<forms
name=".ADAuthCookie"
timeout="10" />
</authentication>
<authorization>
<deny users="?" />
<allow users="*" />
</authorization>
<membership defaultProvider="MyADMembershipProvider">
<providers>
<add
name="MyADMembershipProvider"
type="System.Web.Security.ActiveDirectoryMembershipProvider,
System.Web, Version=2.0.0.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
attributeMapUsername="sAMAccountName"
connectionStringName="ADConnectionString"
connectionUsername="MyDomain\AdminUser"
connectionPassword="LotsaLuck99$"/>
</providers>
</membership>
<!--
The <customErrors> section enables configuration
of what to do if/when an unhandled error occurs
during the execution of a request. Specifically,
it enables developers to configure html error pages
to be displayed in place of a error stack trace.

<customErrors mode="RemoteOnly"
defaultRedirect="GenericErrorPage.htm">
<error statusCode="403" redirect="NoAccess.htm" />
<error statusCode="404" redirect="FileNotFound.htm" />
</customErrors>
-->
</system.web>
</configuration>

Thanks in advance

Silly me - I forgot to set the Application Name in IIS Manager.
