You can do this via the query section of LANDesk console.
You should be able to utilise the version of the Inventory scanner that is found under Computer > LANDesk Management > Inventory > Scanner > Version.
Thanks for reply, but I mean the serive pack level of Windows XP(0,1,2 or 3) and not the servicepack level of the inventory scanner.
The location of the XP Service pack information is under Inventory->OS->NT Info. It will show up what service pack that client has. You can create a report and query that location for the information that you need.
Thanks for your quick reply! This gives me the information I need
