Since Windows was upgraded on the endpoint machine agent scanning with auto-remediation is failing.
The most likely root cause is that the OS upgrade interfered with the deployed agent installation or the required environment settings. You have to redeploy the agent through the GFI LanGuard console:
- Uninstall GFI LanGuard Agent on the target machine.
- Deploy GFI LanGuard Agent on the target machine.
- Ensure that Required Settings to Scan a Machine and Successfully Install Missing Patches Using GFI LanGuard are in place.
Verify that agent scanning and auto-remediation operations are no longer failing. If the issue persists, contact GFI LanGuard Support.
