I am trying to make some enhancements to a production web app. After quite a bit of unit testing 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:

• the primary web app
• the "primary" webservice (the home page tries to invoke this WS)
• a "secondary" webservice (not yet a problem because home page does not invoke this WS)

I get the following when I try to browse to the home page of the web app typing this into my browser: link text

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 is a bit of the corresponding 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 configured things incorrectly on the staging server. The staging server is Win Server 2003 ServicePack 2 running IIS 6.0. When I published the primary site and the 2 webservices on the staging server called MOJITO I created the physical directories for each on the D drive. Then using INETMGR, I configured the following virtual directories:

• zVersion2
• zVersion2wsSQL
• zVersion2wsEmergency

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

Can my staging versions of the above webservices (named zVersion2wsSQL and zVersion2wsEmergency respectively) co-exist on the same web server with the same IP address?

Please note that when I test the zVersion2wsSQL webservice independently (from INETMGR right-mouse and click Browse) it works as expected (i.e. presenting all the methods of the webservice) like this snippet:

• GetMessageByType MessageName="Get_x0020_Message_x0020_By_x0020_Type"

I can test this webmethod by clicking on it and it presents the Test dialog (because it takes a simple datatype and I am invoking 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 fear I may have rambled with too much information so I will stop but I hope someone can help me as I cannot understand why this request results in a "not found". Thanks.
