Hello Marc,

I have just recognized, that if I shutdown samba4 on the DC, the client
is currently connected to, the login suddenly proceeds from the welcome
screen where it would otherwise have remained forever. I have tested it
with all three DCs and it is always the same result.

Do you have an idea what could be the cause of the problem, or can you
propose how I can troubleshoot in more detail ?

Thank you for your kind help

best regards
