Workgroup is an agentless, fully automated scanning target that scans any Windows workgroup submitted by you. The computers must be visible in your Network browser, which you can access using Windows Explorer, to be scanned by a Workgroup scanning target. Every 15 minutes, the Workgroup target retrieves a list of computers that are visible in the Network browser and that belong to the workgroup you've specified. Newly logged on computers that have not been scanned in the last 20 hours are added to your scanning queue.
You can submit an unlimited number of these targets for scanning. To submit a Workgroup target for scanning, hit the Add Scanning Target button in the following section of the web console and choose the Workgroup scanning type in the resulting popup: Scanning\Scanning Targets. You'll need to submit the name of the workgroup to be scanned. Optionally, you can submit a description for the scanning target as well. If you have multiple scanning servers, there will be multiple configuration tabs on the Scanning Targets page, one for each server.
