Windows 10 update deployment error

Hello,

i have a problem with windows 10 clients, i cant update (deploy) the forticlient to a new version with the ems server, i get the following error in the logs (forticlient on Windows 10):

a network error prevent updates from being downloaded

i have created a gpo also like in the forticlient manual:

Windows installer Automatic start

Remote Registry Automatic start

Task Scheduler Automatic start

Firewall:

Remote Scheduled Tasks Management (RPC-EPMAP)

File and Printer Sharing

Remote Scheduled Tasks Management (RPC)

It was working with Windows 7, but with windows 10 i cant deploy a new forticlient version!

I also get an alert email from the server that a lot endpoints are out-of-date and there are pending upgrades to 6.2.1 (120 clients).

Kind regards,

mpuff
