LsAgent scans don't generate scanning errors as the agent has the required admin rights to locally scan the machine.
If you are scanning your devices with LsAgent and see scanning issues like RPC unavailable, firewall issues, access denied, etc., these are most likely the result of agentless scans that are still targeting the concerning devices.
To resolve this, ensure that your agentless scanning targets under Scanning > Scanning Targets no longer target the machines you're scanning with LsAgent. This can be done by either removing or disabling the concerning scanning targets or adjusting their scope.
Please note that setting up a scanning exclusion for the concerned devices will prevent the LsAgent scans from being imported, and no record is created in the database.
