[Samba] join member failed

[Corrado Ravinetto]

Hi guys
When i try to add a member to my domain (samba 4.17.3) receive ERROR_DNS_UPDATE_FAILED
Then i added manually record A to dns, i can see my dm connected  to dc with smbstatus
but i can't access to my member anymore, what can i do ??
Sorry but it's very urgent
thanks

[root at dm midom]# samba-tool domain join LXmidom.COM MEMBER -U administrator --server=dc4 -v
