Issue with ConfigurationSettings.AppSettings

[Celebrate]

My application works fine when I run it locally but when I transfer it
to our NEW Windows 2003 Web Edition server, I get a strange error.
I've isolated the problem to when I issue a
ConfigurationSettings.AppSettings["foo"] call.

My guess is, there's a security setting that I'm missing on my Server
but what?? I've spend hours trying to debug this; help on this would
be greatly appreciated...

Here's the error I get:

Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of
the current web request. Please review the stack trace for more
information about the error and where it originated in the code.

Same page calling this?
Is the Web.Config getting updated on the server? and the right one in the
right location?

Here's the Web.Config file, and yes I checked and it's consistant on
both machines.

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="EmailFrom" value="ww*@foo.com"/>
<add key="EmailTo" value="fo*@foo.com" />
</appSettings>

<system.web>

<!-- DYNAMIC DEBUG COMPILATION
Set compilation debug="true" to enable ASPX debugging.
Otherwise, setting this value to
false will improve runtime performance of this application.
Set compilation debug="true" to insert debugging symbols
(.pdb information)
into the compiled page. Because this creates a larger file
that executes
more slowly, you should set this value to true only when
debugging and to
false at all other times. For more information, refer to the
documentation about
debugging ASP.NET files.
-->
<compilation
defaultLanguage="c#"
debug="true"
/>

<!-- CUSTOM ERROR MESSAGES
Set customErrors mode="On" or "RemoteOnly" to enable custom
error messages, "Off" to disable.
Add <error> tags for each of the errors you want to handle.

"On" Always display custom (friendly) messages.
"Off" Always display detailed ASP.NET error information.
"RemoteOnly" Display custom (friendly) messages only to
users not running
on the local Web server. This setting is recommended for
security purposes, so
that you do not display application detail information to
remote clients.
-->
<customErrors
mode="RemoteOnly"
/>

<!-- AUTHENTICATION
This section sets the authentication policies of the
application. Possible modes are "Windows",
"Forms", "Passport" and "None"

"None" No authentication is performed.
"Windows" IIS performs authentication (Basic, Digest, or
Integrated Windows) according to
its settings for the application. Anonymous access must be
disabled in IIS.
"Forms" You provide a custom form (Web page) for users to
enter their credentials, and then
you authenticate them in your application. A user
credential token is stored in a cookie.
"Passport" Authentication is performed via a centralized
authentication service provided
by Microsoft that offers a single logon and core profile
services for member sites.
-->
<authentication mode="Windows" />

<!-- AUTHORIZATION
This section sets the authorization policies of the
application. You can allow or deny access
to application resources by user or role. Wildcards: "*"
mean everyone, "?" means anonymous
(unauthenticated) users.
-->

<authorization>
<allow users="*" /> <!-- Allow all users -->
<!-- <allow users="[comma separated list of users]"
roles="[comma separated list of roles]"/>
<deny users="[comma separated list of users]"
roles="[comma separated list of roles]"/>
-->
</authorization>

<!-- APPLICATION-LEVEL TRACE LOGGING
Application-level tracing enables trace log output for every
page within an application.
Set trace enabled="true" to enable application trace
logging. If pageOutput="true", the
trace information will be displayed at the bottom of each
page. Otherwise, you can view the
application trace log by browsing the "trace.axd" page from
your web application
root.
-->
<trace
enabled="false"
requestLimit="10"
pageOutput="false"
traceMode="SortByTime"
localOnly="true"
/>

<!-- SESSION STATE SETTINGS
By default ASP.NET uses cookies to identify which requests
belong to a particular session.
If cookies are not available, a session can be tracked by
adding a session identifier to the URL.
To disable cookies, set sessionState cookieless="true".
-->
<sessionState
mode="InProc"
stateConnectionString="tcpip=127.0.0.1:42424"
sqlConnectionString="data
source=127.0.0.1;Trusted_Connection=yes"
cookieless="false"
timeout="20"
/>

<!-- GLOBALIZATION
This section sets the globalization settings of the
application.
-->
<globalization
requestEncoding="utf-8"
responseEncoding="utf-8"
/>

</system.web>
</configuration>
