WCF服务错误

大家好，
我有WCF服务.我想在C#类库中使用它.
为此，我已将此WCF添加为服务参考.
我使用了类通道工厂，并提供了所有必要的凭据.
频道已完美打开，但出现以下错误.
"HTTP请求已使用客户端身份验证方案Basic进行了未经授权的操作.从服务器收到的身份验证标头为
基本领域="Idc安全性/idc/idcplg".

有人可以建议我做错了什么地方吗?
谢谢

Hi every one,
I have WCF service. I want to use that in the C# class library.
for this i have added this WCF as service reference.
I have used the class channel factory and provided all the necessary credentials.
Channel opend perfectly but I am getting the following error.
"The HTTP request is unauthorized with client authentication scheme Basic. The authentication header received from the server was
Basic realm="Idc Security /idc/idcplg".

Can any one suggest me where I did wrong?
Thank you
