> I did try to use web serives wizard, it ask me to key in virtual directory. Since I don't have IIS, in my network or local machine, i don know what should I enter to this field.

You have to have IIS to get this to work. A virtual directory maps to a real directory on the IIS machine. For instance, you can have a directory d:\MyWebService on a local drive. You can create an IIS virtual directory that maps to this, so that when a user types http://myserver.com/MyWebService/default.asp, the request is mapped to d:\MyWebService\default.asp on the server.
