Hi, your NetScanner used to allow the assignment of friendly names, however, that feature is no longer working. When I right click on a device, the Assign Friendly Name choice is shaded light gray, meaning, this choice cannot be made. Why is this no longer working?
Please check the columns selected for "Identify by" in Options - Friendly Names (see below). Most likely you simply need to select some columns there, so the NetScanner knows which columns serve as the key for assigning friendly names.
The setting you are looking for is Friendly Names/Comments under Options in the main menu, as shown below. Once you have enabled it and selected the columns for identification, you will be able to assign friendly names.
