getwithrob,
The scan in the Network Sonar tool can not be scheduled but this technology is being used in the Orion discovery engine and based on what you are trying to accomplish, maybe looking at a license of Orion would make sense. Scheduled Discover is a feature that SolarWinds said they are working on in the following post: What SolarWinds is working on in Orion.Thanks,Jason HensonLoop1 Systemshttp://www.loop1systems.com/
