WCF AllowNTLM .net 3.5sp1 and IIS7.5

I am getting the following error using WCF, calling the a WCF Service on another server.

An error (The request was canceled) occurred while transmitting data over the HTTP channel.

The followi开发者_开发百科ng Services worked on a IIS7 Box on .net3, but we have recently upgraded to IIS7.5 and .net 3.5sp1, if I remove the AllowNtlm attribute out of the Config, the call gets further but does not pass allow the service to do a double hop to the database, i then get the follow error.

'NT AUTHORITY\ANONYMOUS LOGON'.

I have enclosed a copy of the client app.config, which worked using iis7, but

<?xml version="1.0" encoding="UTF-8"?>

This is the Server Config, any ideas?

<?xml version="1.0"?>
<configuration>
  <system.serviceModel>
    <services>
      <service behaviorConfiguration="CacheManagementBehavior" name="Iris.WebServices.CacheManagement.CacheWebService">
        <endpoint address="" behaviorConfiguration="" binding="basicHttpBinding"
         bindingConfiguration="basicHttpBinding_CacheManagement" contract="Iris.WebServices.CacheManagement.CacheWebService" />
        <endpoint address="mex" behaviorConfiguration="" binding="basicHttpBinding"
         bindingConfiguration="basicHttpBinding_CacheManagement" contract="IMetadataExchange" />
      </service>
    </services>

            <transport clientCredentialType="Windows"/>
            <message clientCredentialType="UserName"/>
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="CacheManagementBehavior">

          <serviceMetadata httpGetEnabled="True"/>
          <serviceDebug httpHelpPageEnabled="true" includeExceptionDetailInFaults="true"/>

        </behavior>a
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

We managed to resolve the issue, by removing ServicePrincipleName from the config
