OK sorry i wanted to send it in private but forgot at the last minute.
10.12.1.4 is the machine running the Eset Admin console. It is a Windows 2012 server. Maybe an update has changed something.
I will have a look.
Thanks for your help !
By the way i didn't know the updates were being made through the admin console machine. It seems obvious for bandwidth reasons, but i thought i needed to "activate" it in some way, and i did not see any feature like this on the console
