How to track the synchronization of the program?

Question

Data synchronization

Hello!
I wondered how you can track when the program is synchronized by standard windows tools? And is it possible to prohibit her from using the Internet for a while without disconnecting.
In my case, if you turn off the Internet connection, the program writes that the synchronization attempt failed and at the same time it continues to work.
I want to try to disconnect it from the network without shutting down the computer completely.
How to do it? I don't expect an absolute solution from you. Just tell me which way to dig)))

Answer 1

block the program from accessing the network with a firewall.
