[Error] WCF: SOAP security negotiation
WCF 服务是启动了，包括三种binding: wsHttpBinding, basicHttpBinding, netTcpBinding.
但当使用wcftestclient进行测试的时候，唯有basicHttpBinding 工作正常，其它两种报错误。错误与
wsHttpBinding:
SOAP security negotiation with 'http://localhost:8001/WCFService' for target 'http://localhost:8001/WCFService' failed. See inner exception for more details.
netTcpBinding:
A call to SSPI failed, see inner exception.

原因：印象中我前不久在IE中把所有的证书都清空了，估计跟这个操作有关，导致Certificate Chain有问题。
