I implemented Scriptlogic last year, having only batch files (NOT scripts) in place. We have 900 users. It has been an extremely worthwhile experience and has already paid us back in terms of time saved by its ease of use and speed of deployment to user desktops.
For the NT and 2000 workstations in our domain we have easily implemented sercurity and locked desktops via Scriptlogic.
Finally, and importantly, they are tops at after sales & support
