System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse error with HTTP status 404

I am trying to make some improvements for a production web application. After quite a bit of testing the modules on my WinXP IIS 5.1 development machine, everything works on my localhost, so I used the Visual Studio 2008 PUBLISH dialog on my Dev PC to push the following projects to a staging server:

• main web application
• the "primary" web service (the home page tries to call this WS)
• the "secondary" webservice (not a problem yet, because the homepage doesn't call this WS)

I get the following when I try to go to the home page of a web application by typing this in my browser: myUglyURL

Server Error in '/zVersion2' Application.
The request failed with HTTP status 404: Not Found.

Version Information: Microsoft .NET Framework Version: 2.0.50727.3607; ASP.NET Version: 2.0.50727.3082

Here's some relevant source code:

Public wsZipeee As New ProxyZipeeeService.WSZipeee.Zipeee
Dim dsStandardMsg As DataSet  
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles  MyBase.Load
    If Not Page.IsPostBack Then
        LoadMessage()
    End If
End Sub

Private Sub LoadMessage()
    Dim iCnt As Integer
    Dim iValue As Integer

    dsStandardMsg = wsZipeee.GetMessageByType(BizConstants.MsgType.Standard)
End Sub

      

        
        
        
      

    

I suspect I may have misconfigured the files on the staging server. The staging server is Win Server 2003 ServicePack 2 with IIS 6.0. When I published the main site and 2 web services on the MOJITO staging server, I created physical directories for each of the D drives. Then, using INETMGR, I configured the following virtual directories:

• zVersion2
• zVersion2wsSQL
• zVersion2wsEmergency

All of the above is configured to use a new application pool that I configured and named zVersion2aspNet20 . The default website for this MOJITO device is configured to use ASP.NET 1.1 and the IP address is set to (All Unassigned) . The production versions of the last 2 web services run on the MOJITO machine (ZipeeeService and EmergencyService respectively).

Can my intermediate versions of the aforementioned web services (called zVersion2wsSQL and zVersion2wsEmergency respectively) coexist on the same web server with the same IP address?

Note that when I test the zVersion2wsSQL web service myself (from the right and click INETMGR and click Browse) it works as expected (ie presents all the web service methods) like this snippet:

• GetMessageByType MessageName = "Get_x0020_Message_x0020_By_x0020_Type"

I can test this web method by clicking on it and it presents the Test dialog (because it accepts a simple datatype and I call it on localhost (i.e. MOJITO):

**Get Message By Type**

**Test**
To test the operation using the HTTP POST protocol, click the 'Invoke' button. 
Parameter Value 
iMsgType: _______                    [INVOKE button]

SOAP 1.1 ....etc. 

      

        
        
        
      

    

I'm afraid there might be too much information, so I'll stop, but hope someone can help me as I don't understand why this query results in "not found". Thank you.
