In the Scanning > LsAgent Scanning section of the Lansweeper web console, you can divide machines scanned with LsAgent into groups, for example your Windows workstations. Under the Configuration tab for each group, you can select the option LsAgent Only, enabling this setting will exclude assets in this group from agentless scanning. They will only be updated by LsAgent scans.
