macOS keeps changing computer name

I've got a popup about there being two computer with the same name on the network.

The OS then change the name to (2), (3), etc.


I know for sure that there's not two computer with the same name on the network.


What can I do?

MacBook Air (13-inch, Early 2014), macOS High Sierra (10.13.1)
