VPN Server => ClearOS
RDP Server => Windows Server 2016 with Kaspersky Small Office Security
Clients => Windows 10/XP with Kaspersky Internet Security
Occasionaly, clients cannot print without any error message.
I have to disable Kaspersky on both server and client, and restart VPN & RDP connection on client to make printing work again.
Only then I can enable Kaspersky once again.
Sorry for my bad English...
