ZENworks is the way to go. If you are running OES2, do you know if you purchased Novell Open Workgroup Suite (NOWS)? It comes with ZENworks 7 that runs great on OES2-Linux (SLES). If you don't own NOWS, you can still download ZEN7 Desktop Management and put into place with a (I believe) 60-day eval. At the end of 60, it stops...but you won't want it to once you get it working and doing desktop lock down, application deployment, and a bunch of other things (inventory, imaging and remote control).
I've used and taught classes on every version of ZENworks in existence...it is the world's best Desktop, Server, Handheld, Linux, Patch and Inventory Management suite out there.
