web services calling services simultaneosly problem in .net 2.0

i m facing a problem
we are using desktop client and webservices
in that client request the a webservice async
that remains on server until a specific condition is satisfied
and rest of the web services are called syncronsly
these services run on localhost without any problem
but if client and server machines are diffrent it hangs the application
dont knw wht is the reasn and after some time operation has timed out exceptions come
let me tell u one more thing
both the services are using different sessions
thanx in advance for ur help 

i have made sample application to test the scnerio
closer to my application
here is client and server side code

client is
Public Class Form1
    Private WithEvents wsAsync As New localhost1.AsyncService
    Private WithEvents wssync As New localhost.SyncService
    Private urltoReplace As String = "http://khalid/" 'this url will b replaced by localhost
    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        wsAsync.Url = wsAsync.Url.Replace("http://localhost/", urltoReplace)
        wssync.Url = wssync.Url.Replace("http://localhost/", urltoReplace)
        wsAsync.CookieContainer = New Net.CookieContainer
    End Sub
    Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

    End Sub
    Private Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
    End Sub
    Private Sub wsAsync_HelloWorldCompleted(ByVal sender As Object, ByVal e As localhost1.HelloWorldCompletedEventArgs) Handles wsAsync.HelloWorldCompleted
    End Sub
    Private Sub wssync_HelloWorldCompleted(ByVal sender As Object, ByVal e As localhost.HelloWorldCompletedEventArgs) Handles wssync.HelloWorldCompleted
    End Sub
End Class
server side is
sync service is
Public Class SyncService
     Inherits System.Web.Services.WebService

    <WebMethod(enablesession:=True)> _
    Public Function HelloWorld() As String
        Return "Hello World"
    End Function
async service is
Public Class AsyncService
     Inherits System.Web.Services.WebService

    <WebMethod()> _
    Public Function HelloWorld() As String
        While True
        End While
        Return "Hello World"
    End Function
End Class
now client and server should b different

 One way of shedding some light on the problem is to use the logging feature of Web Services Enhancements to track the message going into and the responses from the web service.

Calling a Web Service from a Web Service
Hello,I was looking for some feedback on calling a web service from within a web service. I've heard that it's not good practice (or not possible). I have a scenario where I think it might make some sense.Within our infrastructure, we've created a web service that handles incoming updates on the statuses of all processes. This has proven to be a good thing since it allows applications to communicate across server to make status updates. It's also used by third party developers and applications to communicate with our infrastructure.Along these lines ... we are planning to create a new compon...

Web Service calls .NET 2.0
I have an ASP.NET application in .NET 1.1 that makes a web service call using the Begin{WebMethod} call and then returns to the page and redirects to another page.  The Async callback is returned later when this is done and I log any errors that this web method call may have had to the event log.  The web page does not wait for the response because it's role is to fire it off and then go on.  I am trying to move to .NET 2.0 and have an issue where the Async call for 2.0 will not allow me to redirect until the web service has completed.  I do not need a response from m...

Can you call a web service from a web service?
I am trying to create a web service that itself consumes a 3rd party web service outside of our corporate firewall - so basically a web service consuming another web service.  I can consume this outside web service directly in an ASP.NET application without a problem.  But because the code is long and cumbersome, I wanted to provide our GUI developers an easy way to get all of the data they need from one source.  So I thought I could create an internal web service that would do a lot of things (query internal systems, for example) as well as consuming this external service.&nb...
