How to change the network security zone for ESET Endpoint Security:

Open ESET Endpoint Security from the taskbar or start menu
In the left menu, click Setup
In the middle screen, click Network
Under Connected networks you will see the network you are currently using
Underneath in blue it will tell you if it thinks this network is safe (Home/Work network) or unsafe (Public network)
If you are at home or work, and it says Public, click the blue text to change the setting
If the setting is correct, you don't need to do anything
Close ESET
Done!
