你好，

>>使用客户端身份验证方案"Ntlm"对HTTP请求进行了未授权的操作.从服务器收到的身份验证标头是"NTLM"

几天前我也遇到了以上错误信息，我通过使用计算机解决了该错误信息 名称或完全合格的计算机名称，而不是WCF服务的IP地址，如下所示: http://YourComputerName:YourPortNumber/Service1.svc .

I also met the above error information some days ago, I solved it by using my Computer name or Fully Qualified Computer name instead of the IP address for the WCF service as following: http://YourComputerName:YourPortNumber/Service1.svc .

如果我的解决方案不适合您，请尝试检查以下类似的线程:
