POWhy do I get Cryptography_CSP_NoPrivateKey when using IIS but not when using VS development server?

Body
copied!<p>I'm doing a web application that utilizes an external web service. This external web service requires me to sign each of my requests. So I'm using <code>WebServicesClientProtocol</code> class and .NET 2.0 by first consuming the external web service and then manually edit the <code>Reference.cs</code> file and change the extended class from <code>System.Web.Services.Protocols.SoapHttpClientProtocol</code> to <code>Microsoft.Web.Services2.WebServicesClientProtocol</code>. Then in the <code>Page_Load</code> method I have the following code:</p> <pre><code>try { // Create the ws endpoint var uriServiceAddress = new Uri("urn:something-wse:something_NNNN"); var uribuilderViaRouter = new UriBuilder("http://xx.xxx.xx/SrvXXX_NNNN/Test.asmx"); var endpointReference = new EndpointReference(uriServiceAddress, uribuilderViaRouter.Uri); // Create the ws client var client = (WebServicesClientProtocol) new Test.Something(); client.Destination = endpointReference; // Read the certificate from MyStore on LocalMachine X509CertificateStore localStore = X509CertificateStore.LocalMachineStore(X509CertificateStore.MyStore); X509SecurityToken securityToken = null; if (!localStore.OpenRead()) throw new Exception("Unable to open localstore for read"); X509CertificateCollection certificateCollection = localStore.FindCertificateBySubjectString("email@subject.test"); if (certificateCollection.Count == 0) throw new Exception("Unable to obtain security token."); securityToken = new X509SecurityToken(certificateCollection[0]); localStore.Close(); // Attach the security toekn to the client request client.RequestSoapContext.Security.Tokens.Add(securityToken); client.RequestSoapContext.Security.Elements.Add(new MessageSignature(securityToken)); // Set the timeouts client.RequestSoapContext.Security.Timestamp.TtlInSeconds = 2 * 60; client.Timeout = 60 * 10 * 1000; // 10 mínútur ættu að duga í flest. // Call the test function DataSet set = ((Test.Something)client).searchMethod("Parameter 1", "Parameter 2"); Label1.Text = User.Identity.Name+ " worked! " + set.Tables.Count + " tables!"; } catch (Exception exc) { Label1.Text = User.Identity.Name + " exception: " + exc.ToString(); } </code></pre> <p>This works fine when I run this using the Visual Studio Development Server but when I change to IIS it stops working and I get the ugly <code>Cryptography_CSP_NoPrivateKey</code> exception.</p> <p><strong>1)</strong> I have already read the Certificate properly into LocalMachine/MyStore using MMC and then I change the private key permissions using WSE 2.0 SP3 so that Everyone has full access to it. You can see this from here:</p> <p><a href="http://www1.ruedenet.is/files/CertError1.png" rel="nofollow noreferrer">alt text http://www1.ruedenet.is/files/CertError1.png</a></p> <p><strong>2)</strong> I also set the property so that the Visual Studio Development Server is used when I debug the application:</p> <p><a href="http://www1.ruedenet.is/files/CertError2.png" rel="nofollow noreferrer">alt text http://www1.ruedenet.is/files/CertError2.png</a></p> <p><strong>3)</strong> Then I run it and get a nice result:</p> <p><a href="http://www1.ruedenet.is/files/CertError3.png" rel="nofollow noreferrer">alt text http://www1.ruedenet.is/files/CertError3.png</a></p> <p><strong>4)</strong> However, when I change the property to use IIS (and have VS create the Virtual Directory) like this:</p> <p><a href="http://www1.ruedenet.is/files/CertError4.png" rel="nofollow noreferrer">alt text http://www1.ruedenet.is/files/CertError4.png</a></p> <p><strong>5)</strong> I also change the authentication method in IIS so that I get logged on (no reason for this really):</p> <p><a href="http://www1.ruedenet.is/files/CertError5.png" rel="nofollow noreferrer">alt text http://www1.ruedenet.is/files/CertError5.png</a></p> <p><strong>6)</strong> So I get asked for a windows logon:</p> <p><a href="http://www1.ruedenet.is/files/CertError6.png" rel="nofollow noreferrer">alt text http://www1.ruedenet.is/files/CertError6.png</a></p> <p><strong>7)</strong> And then my page runs and produces the error:</p> <p><a href="http://www1.ruedenet.is/files/CertError7.png" rel="nofollow noreferrer">alt text http://www1.ruedenet.is/files/CertError7.png</a></p> <p>If you could help me with this I would surely appreciate it. I have already spent hours on it and I don't want to spend more time if I'm making a fundamental error that you guys can see. BTW: I'm developing using Visual Studio 2008 on Windows Server 2008 with UAC turned off :-)</p> <p>Really looking forward to hearing from you guys. Thanks.</p>
