Hi, in Windows XP i access to my webservice with the following VB-Script-Code: dim osoapClient Set osoapClient = CreateObject("MSSOAP.SoapClient") osoapClient.mssoapinit "http://exch2003/exchwebservice/service1.asmx?WSDL" in Vista doesn't exist the Class "MSSOAP.SoapClient". How can i access to the Webservice in Vista? thx & bye Oskar
