WCF security token error - when accessed from asp.net UI

Howdy,

I have a simple WCF service (wshttpbinding) developed using VS2008.

I have an asp.net web page that calls this WCF service. I have included the appropriate parts of web.config files for both. I get the following error when asp.net calls a contract which is in the wcf service.

"The message could not be processed. This is most likely because the action 'http://tempuri.org/IQRMDMSService/GetDistinctCompanies' is incorrect or because the message contains an invalid or expired security context token or because there is a mismatch between bindings. The security context token would be invalid if the service aborted the channel due to inactivity. To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the service endpoint's binding.

WCF web.config file:

Code:

---

<system.serviceModel>
    <!--<serviceHostingEnvironment aspNetCompatibilityEnabled="true">
    </serviceHostingEnvironment>-->
    <bindings>
      <wsHttpBinding>
        <binding name="WSHttpBinding_IQRMDMSService" maxReceivedMessageSize="100000000" closeTimeout="00:10:00" openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" transactionFlow="true">

        </binding>

Web.config of the asp.net client:
