本文描述了在实践WebService编程中遇到的HTTP状态401：未授权错误，并详细记录了解决过程。作者在代码中设置了凭据，但仍然收到错误。问题在于IIS设置，需要启用“基本身份验证”。文章强调了代码与Web服务配置的一致性对于避免此类错误的重要性。

Recently I wanna practice some web service program. I stucked at one error The request failed with HTTP status 401:Unauthorized. .

I had set up the credential in my code like following, so my program should have right to excute

        Dim objWS As New SoapHeaderTestWS.Service1
        Dim objWSHeader As New SoapHeaderTestWS.HeaderClass
        Dim credCache As New CredentialCache
        credCache.Add(New Uri(objWS.Url), "Basic", _
                                                        New NetworkCredential("Administrator", "pass@word1"))
        objWS.Credentials = credCache

however i still have "HTTP status 401:Unauthorized. ." error.

I found my problem is in IIS setting. I had to check "Basic authentication(password is sent in clear text)".

I guess the reason is simple, because I use "Basic"  authentication type in my code.
So I have to configue my webserivice in IIS to correspond with my code.
