Run a Web Service in IIS

[lalindu]

i simply create a webservice (Add two numbers) in a ASP.NET page usin vb.net 2005. when i run it usin vb.net it runs using some "localhost port"(ex:-"http://localhost:1543/........").so then i can access those methods using that url.but i cant access that from an another machine by typing my IP Address and other <service>.asm x page.
my simple Service is:-
*************** *************** *************** *************** *************** *************** *
Imports System.Web
Imports System.Web.Serv ices
Imports System.Web.Serv ices.Protocols
Public Class Service
Inherits System.Web.Serv ices.WebService

<WebMethod()> _
Public Function add(ByVal a As Integer, ByVal b As Integer) As Integer
Return a + b
End Function

End Class
*************** *************** *************** *************** *************** *************** **
(i use vb.net 2005,windows 2000 SP4,IIS Version 5 )

Isimply copy and paste my web service folder to "\Inetpub\wwwro ot" and run it.

i reseive this error message:-
*************** *************** *************** *************** *************** *************** *
