External Web Service

[John S]

Hi,

I'm trying to connect to an external web service from an ASP.NET page.

I can create the Web Reference and get back the details etc of the available
methods.

I can access these methods from a VB.NET Windows application with the
following code:

Dim loginID As String = "123456"
Dim Password As String = "abcdef"
Dim obj As New O2Test.ELSLocationService
Dim locReq As O2Test.LocationResponse
Dim objProxy As New System.Net.WebProxy
Dim reply As Boolean
Dim NetCred As New System.Net.NetworkCredential("123456", "abcdef")

objProxy.Credentials = NetCred

obj.Proxy = objProxy
reply = obj.validateCredentials(loginID, Password)

However when I paste the same code into a button_click command on the Web
Page I get the error:
The underlying connection was closed: Unable to connect to the remote server.

We are using windows authentication internally without anonymous access.

Can anyone suggest what else I need to do?

Thanks
