Your code should work and give you a formatted fault as per the MSDN example or, if you want a result as in the response sample you posted, then a service like this should do the trick:

Imports System
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
Imports System.Xml.Serialization
Imports System.Xml

Public Class Service1
    Inherits WebService

    
    Public Sub Process()
        Dim detailsNode As XmlNode = Nothing
        Dim actorString As String = Nothing
        Throw New SoapException("BlahBlahBlahBlahBlah", SoapException.ServerFaultCode, actorString, detailsNode)
    End Sub
End Class

A call like this:

should return this:

   
      
         soap:Server
         BlahBlahBlahBlahBlah
         
      
   

You also need to add this to your Web.config file to remove any stacktrace in your fault string:

    
        
        ...
    ...     
...

Also, it's usually not necessary to build the SoapException by hand but throw more appropriate exceptions and let ASP.NET wrap it in a SoapFault. See here for more details: Using SOAP faults.

Use SoapUI to call your method and you should get the above result. Make sure you make a POST on the SOAP endpoint e.g. http://localhost:8080/Service1.asmx and not on the URL of the test page when you click "Invoke" e.g. http://localhost:8080/Service1.asmx/Process as that does not return SOAP formatted responses.
