[Samba] Where am I connecting when using GPO editor?

> When I run on a Windows PC GPO management, to which DC am I connecting to ? My logon server ? To a particular FSMO role owner ?

In the Group policy Management applet, on the tree select your domain then go to "Action" menu and choose "Change Domain Controller". If you choose a particular DC, it will become the default DC until you change it.
