Thank you for your quick response.
root@dc1:~# ucr get dns/backend
samba4
root@dc1:~#
all servers (dc1,dc2,member) have been restartet completely.
The new domain uses the same network-IPs as the old one but different FQDNs.
Some old programs refer to servername and -adress, so I had to use identical servername and IP for the memberserver. Like this:
old member: 10.0.0.20 member.company.intranet
new member: 10.0.0.20 member.corp.int
At no time the memberservers run in parallel, of course. Only the old master came up for some minutes again.
My first post has to be corrected: with that old login to the memberserver the shares can be made visible but not accessable. The only way to access shares is typing the IP into the address bar of windows explorer. Everything else needing a proper DNS is not working, although from Windows I can ping all servers by name or IP successfully.
Here are the outputs of the other commands you have asked for:
