Unhandled exception with Silverlight Application when running from a deployed site.

Question

I have a simple Silverlight application that consists of a DataGrid and a web application, along with using a WCF Service to get the data. Everything works great when running it from the Visual Studio DevServer. Also when running from the deployed IIS application, meaning when I use "http://localhost/SomeApp.aspx" it renders the data perfectly.

But, if I try to use my IP Address instead of "localhost" it gives me the following error:

Microsoft JScript runtime error:
Unhandled Error in Silverlight Application An exception occurred during the operation, making the result invalid.

Check InnerException for exception details.

at System.ComponentModel.AsyncCompletedEventArgs.RaiseExceptionIfNecessary()
at SilverlightApps.PortalService.GetLOBsCompletedEventArgs.get_Result()
at SilverlightApps.MainPage.service_GetLOBsCompleted(Object sender, GetLOBsCompletedEventArgs e)
at SilverlightApps.PortalService.DentalPortalServiceClient.OnGetLOBsCompleted(Object state)

Here is my ServiceReferences.ClientConfig:

<configuration>
<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="BasicHttpBinding_IPortalService" maxBufferSize="2147483647"
                maxReceivedMessageSize="2147483647">
                <security mode="None" />
            </binding>
        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://myComputerName:8000/PortalServices.PortalService.svc"
            binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IPortalService"
            contract="PortalService.IPortalService" name="BasicHttpBinding_IPortalService" />
    </client>
</system.serviceModel>

And here is my web.config from the services application that is deployed on IIS:

<configuration>

<connectionStrings>
    <add name="Portal" connectionString="PortalDev"/>
</connectionStrings>

<system.web>
    <compilation debug="true" />
</system.web>

<system.serviceModel>
    <services>
        <service name="PortalServices.PortalService">
            <endpoint address="" binding="basicHttpBinding" contract="PortalServices.IPortalService">
            </endpoint>
            <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
            <host>
                <baseAddresses>
                    <add baseAddress="http://localhost:8473/PortalServices/PortalService/" />
                </baseAddresses>
            </host>
        </service>
    </services>
    <behaviors>
        <serviceBehaviors>
            <behavior>
                <serviceMetadata httpGetEnabled="True"/>
                <serviceDebug includeExceptionDetailInFaults="True" />
            </behavior>
        </serviceBehaviors>
    </behaviors>
</system.serviceModel>

</configuration>

And my environment is: Windows 7, IIS 7, and Visual Studio 2010.

If anyone could help me with understanding where I may be going wrong here I would greatly appreciate it. I'm curious if it's an authentications issue or what. But like I said before. It works fine when I call the IIS deployed app using "http://localhost/SomePage.aspx" but crashes when I use "http://192.168.1.22/SomePage.aspx". Thanks for the help.
