I need help creating and consuming Web Services internally. These are steps I did.  

1.

created a function to fill dataset  on webapp1 (for web services)


   <WebMethod()> _
    Public Function MyDataset() As DataSet

        Dim constr As String = WebConfigurationManager.ConnectionStrings("myConnectionString").ToString
        Dim con As New SqlConnection(constr)
        Dim ad As New SqlDataAdapter("select *from mytable", con)
        Dim ds As New DataSet

        ad.Fill(ds)

        Return (ds)



    End Function

2. created a proxy class  on my webapp2

   - added a Web Reference then

     on aspx page  


Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        Dim xyz As New Test

        Me.GridView1.DataSource = xyz.MyDataset     <<<<<<<< error The request failed with HTTP status 401: Unauthorized. ???
        Me.GridView1.DataBind()


    End Sub

these are internal web application on my server.

You need to make sure that you set the credentials for your web service.  I'm not exactly sure how to do it in vb, but in C# it would be:

xyz.Credentials = new NetworkCredential("username","password");

you have to add Default credentials
Dim myProxy As localhost.webapp1 = New localhost.webapp1 ()
myProxy.Credentials = System.Net.CredentialCache.DefaultCredentials
