WebHost failed to process a request on IIS 7 windows 2008 when using Windows Mobile - windows

Question

I have developed a webservice using WCF and secured it using NTLM over SSL. I am able to connect successfully using from a visual Studio 2008 form or Web Project. The problem I am having is when creating a smart device project and deploying it on the device.
when I call the service, from client side I get the error: Web Exception
on the server site, when i check the Event Log I get the following Error:
**Sender Information: System.ServiceModel.Activation.HostedHttpRequestAsyncResult/7491627
Exception: System.Web.HttpException (0x80004005): There was no channel actively listening at 'https://mymachine:9011/FrontEndWS/MeterReadingService.svc/$metadata'. This is often caused by an incorrect address URI. Ensure that the address to which the message is sent matches an address on which a service is listening. --->

Cannot figure out why this is happening from mobile devices but works fine from a PC.
