    copied!<p>Solution to original problem (below) may have been discovered. I commented out</p> <pre><code>&lt;identity&gt; ... &lt;/identity&gt; </code></pre> <p>tag in the app.config file for the client. But I'm not sure if this is going to cause other problems, if it does, could someone let me know?</p> <hr> <p>I've been following the <a href="http://msdn.microsoft.com/en-us/library/ms730144.aspx" rel="nofollow noreferrer">Getting Started tutorial</a> at MSDN for WCF.</p> <p>I'm using Visual Studio.net 2008 on Vista x64. The Service program is running just fine. However, the client is having issues.</p> <p>When I run the client I get this exception:</p> <blockquote> <p>SecurityNegotiationException was unhandled SOAP security negotiation with '<a href="http://localhost:8000/ServiceModelSamples/Service/CalculatorService" rel="nofollow noreferrer">http://localhost:8000/ServiceModelSamples/Service/CalculatorService</a>' for target '<a href="http://localhost:8000/ServiceModelSamples/Service/CalculatorService" rel="nofollow noreferrer">http://localhost:8000/ServiceModelSamples/Service/CalculatorService</a>' failed. See inner exception for more details.</p> </blockquote> <p>The inner exception message says:</p> <blockquote> <p>"The Security Support Provider Interface (SSPI) negotiation failed."</p> </blockquote> <p>My code is pretty much exactly the same as the example's. I've never really done anything with web services or WCF or anything similar. Anyone know how I could go about fixing this? Thanks.</p> <p>Edit - I forgot to mention where the exception is thrown... In the client's Main method:</p> <pre><code>CalculatorClient client = new CalculatorClient(); double value1 = 100.00; double value2 = 15.99; double result = client.Add(value1, value2); //This is the line that throws the error //... </code></pre> <p>I added client.Open(); right after the client init, because I searched Google and someone was having problems too and that helped him, but when I do that the same exception is thrown on the new line.</p>
