After an HUGE problem fortunatetly I always make m’y tests on lab structure, ive take an snapshot rewind, and erased the second dc. I had to depromote twice the win10 vm and promote again… magic all my roaming profiles are up and running again, I will stick with 1 nethserver for instance, and try another aproach, to maybe point m’y BDC to a shared Nas folder between all the future NS failover… I dont know for instance… I had to recheck m’y ntp server and reboot gpo synchronisation errors, after check nethserver time… The gpo worked sweet… I’m in surveillance mode
