Hello Zolo,
unfortunately I can't confirm. Using R81.069.0000 throughout the currently running DC migration to Windows Server 2022 I can only fetch them via the remaining 2016 DCs, not directly. And then I can't get them connected neither via IP, nor hostname or FQDN.
Fetching via IP works instantly while hostname and fqdn needs about 30 secs.
Error states "Unable to connect; please check connectivity with server and server firewall configuration". I can see tcp/udp 389 but no 636. Nothings getting dropped, tried debug options via regedit but got not significant more info other than "ErrCode (1722)" which seems to be a dead end.
Any tipps appreciated
Jöran
