We've got a number of thin clients, and using the Wyse Device Manager I get the serial number from them.

However this is not a valid service tag to log a Service Request with.

These machines are distributed over a wide area & there is not always someone at the site who could pick up the machine & try to find the sticker (which, there sometimes isn't one).

How can I  get the required service tag?

Cheers,

Ed
