WCF 'A Call to SSPI Failed, see inner exception'

Question

I had a self-hosted win service WCF installed and running at one point.

Naturally, I had to make some changes. So I changed the base address back to my local workstation and made the changes. It worked fine.

Now it's time to redistribute and... Well... It keeps hosing and I can't figure it out.

From the app.config file:

<system.serviceModel>
<services>
  <service behaviorConfiguration="ExStreamWCF.Service1Behavior"
    name="ExStreamWCF.Service1">
    <endpoint address="" binding="netTcpBinding" bindingConfiguration=""
      contract="ExStreamWCF.IService1">
      <identity>
        <dns value="Devexstream-2" />
        <!--<dns value="vmwin2k3sta-tn2" />-->
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexTcpBinding" bindingConfiguration=""
      contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="net.tcp://Devexstream-2:8080/Service" />
        <!--<add baseAddress="net.tcp://vmwin2k3sta-tn2:8080/Service" />-->
      </baseAddresses>
    </host>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="ExStreamWCF.Service1Behavior">
      <serviceMetadata httpGetEnabled="false" />
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>

From the web.config file (long story):

  <system.serviceModel>
    <services>
  <service behaviorConfiguration="ExStreamWCF.Service1Behavior"
    name="ExStreamWCF.Service1">
    <endpoint address="" binding="netTcpBinding" bindingConfiguration=""
      contract="ExStreamWCF.IService1">
      <identity>
        <dns value="Devexstream-2" />
        <!--<dns value="vmwin2k3sta-tn2" />-->
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexTcpBinding" bindingConfiguration=""
      contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="net.tcp://Devexstream-2:8080/Service" />
        <!--<add baseAddress="net.tcp://vmwin2k3sta-tn2:8080/Service" />-->
      </baseAddresses>
    </host>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="ExStreamWCF.Service1Behavior">
      <serviceMetadata httpGetEnabled="false" />
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>

Any guesses on what I'm doing wrong?

Thanks tomasr, it was a misconfigured SPN.

Too bad there's no functionality on this site to close your own question, I'll have to wait 2 days to choose this one :-)

Thanks again!
