錯誤：遠程服務器返回錯誤：（401）未授權

Question

當我嘗試訪問調用WCF函數的窗體時，我不斷收到此錯誤。 其實它的工作原理我的本地機器上，但是當它在服務器上，這種事情發生:(

此錯誤是由解決改變我的web.config內的安全設置

<security mode="TransportCredentialOnly"> 
     <transport clientCredentialType="Windows" proxyCredentialType="None" 
     realm="" /> 
     <message clientCredentialType="UserName" algorithmSuite="Default" /> 
</security>
