Hi,

I have a web service which works fine under the ASP.NET development
server (on default port 4219) and also from an ASP.NET client with a
reference to the deployed service.  However, I'm unable to access the
service from a windows application.  I have only used ASP.NET in the
past to consume a web service, and hope I am just doing something
stupid.  I've verified the service is running under IIS and I've set
the permissions to public access.  I've also tried accessing the
service through both localhost and the computer name, but get the same
"Unable to connect to the remote server" error.

An ASP.NET form with a button has the following code behind and works
fine:
 Protected Sub Button1_Click(ByVal sender As System.Object, ByVal e
As System.EventArgs) Handles Button1.Click
       Dim di As dealerInterface.DealerInterface
       di = New dealerInterface.DealerInterface
       Dim xn As System.Xml.XmlNode
       xn = di.SendQuote("<?xml version=""1.0"" encoding=""utf-8"" ?

       TextBox2.Text = xn.OuterXml()
   End Sub

The *exact* same code in a VB windows app (using the same web
reference URL) gives the following exception:

System.Net.WebException was unhandled
 Message="Unable to connect to the remote server"
 Source="System"

Granted, "TextBox2" is a different underlying control in the two apps,
but the Windows app doesn't even get to this line, as the exception is
thrown on the web service method invocation.  Essentially I only have
this line in there to see the correct result from ASP.NET.

I would really appreciate any help!!

Thanks very much,
Scott
