Problem with WCF and MSMQ

I have a WCF service that I have exposed a msmq binding.  The msmq is setup as a public queue - I have grated full control to 'everyone'.  I have a .net 3.5 project that I add the wcf service as a service reference.  It finds it and adds all the necessary bindings.  The service is on a server on our domain.  I can attach to and interact with the service.  I deploy the web site to the same server that the WCF is running on.  The entire site work fine until I call the service, and I get the messaage below.  I have checked and there are 2 certificates on the queue - one for admin and another for the developer machine name.  I have tried every different permission setting I can think of - what do I need to do to get this to work?

An error occurred while sending to the queue: No internal Message Queuing certificate exists for the user. (-1072824273, 0xc00e002f).Ensure that MSMQ is installed and running. If you are sending to a local queue, ensure the queue exists with the required access mode and authorization.

Are you using (Windows Server 2003 + MSMQ 3) or (Windows Server 2008 + MSMQ 4) ?

If you are using (Windows Server 2003 + MSMQ 3) I would not recommend using public queues.
Use private queues.

Also I would need to see your client and server side msmq bindings.

Hello thanks so much for gettign back to me.. we are running Windows Server 2003 with MSMQ 3.  I thought that public queue where for exhcanges from machines from one server on the network to another.  In this case we are on a testing server, so the www site is talking to the WCF on the same box - in production it will be the WCF on one box and the WWW app on another - does that make a difference?  Please find my config for both client and service.. thanks so much for your help.  As an fyi our service is kind of central email sender - we have many different business process that need to pump out email so we decided to make all email be processed and sent from this service..

Public queues are simply queues that get published in Active Directory and are therefore serachable or discoverable.
However, there are issues with them so I would avoid using them if possible.

To test the service I would start off with private queues and set up a test MSMQ Binding that implements no security (see below).

Once you are happy with it working implement security on the binding properly and retest.

There is no really good reason to use public queues.
In fact, if you read Juval Lowy's book on WCF, he specifically recommends against it.


<endpoint address="net.msmq://localhost/private/MyQueueName"
            binding="netMsmqBinding" bindingConfiguration="NoMSMQSecurity"
            contract="IMyContract" name="MSMQTest" />
 
<netMsmqBinding>
    <binding name="NoMSMQSecurity" >
       <security mode="None" >
       </security>
    </binding>
</netMsmqBinding>
