You need to kick of vulscan.exe from the ldclient directory. If you look at the properties of the secuirty scan shortcut on a client machine you can see the default only has the showui switch but there are heaps more if you run vulscan /? or have a look at http://community.landesk.com/support/docs/DOC-2337
"C:\Program Files (x86)\LANDesk\LDClient\vulscan.exe" /showui=true
Of course its vulscan, im having a blonde moment, which is hard when your not blonde!
