Why is 'Scan OU Recursively' greyed out when scanning the domain with GFI LanGuard? Author: Luis Fernandes October 27, 2020 18:34 Updated Answer The option 'Scan OU recursively' is only available if you open the Properties of any OU. By default, Network Discovery scans the whole domain, including all the OUs. The check box is used to synchronize a specific OU and the sub-OUs.

While Accessing the Central Management Server Console Can GFI LanGuard detect the log4j vulnerability (CVE-2021-44228)? Why does the information on a scan seem to be static and vulnerability status is not changing?
