Hello Yi,

I think there is no "good" solution for your problem using
a webservice only - webservices are not designed for such
purpose at all!

Maybe you have the possibility to access any scheduling-
components - but what are your concerns regarding the
windowsservice AND webservice solution?

Regards

Tom
