Hi, We were running Samba-AD - Version 4.7.6 for over 2 years without any errors. We have 4 Domain Controllers in our setup and DNS is BIND_DLZ (BIND 9.9.4). Off late (since 8th June 2019) we upgraded the Samba-AD version to 4.10.4 and all of sudden we started receiving the error "RPC Server not available" when we are trying to join the new PCs to domain. After multiple attempts the PC gets added to domain. We restart samba service on the log on server, the error goes off. We are receiving the same error whenever we are trying to add a new user or modify a user attribute in RSAT. When this error comes, we have to restart the RSAT server multiple times to start functioning again. There is no specific pattern for this appear to appear. Once we noticed that /etc/krb5.conf was modified and we replaced it with the file krb5.conf available in "/usr/local/samba/private/". That seemed to have solved the issue. But after about a week or so, the same error has resurfaced. This is somewhat strange. Is there is any specific reason for this error? How do we fix it? My smb.conf is as shown below. -------------------------------------------------------------------------------------------------- Global parameters [global] ??????? netbios name = PDC ??????? realm = XXXX.COM ??????? server role = active directory domain controller ??????? workgroup = XXXX ??????? server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbindd, ntp_signd, kcc, dnsupdate ??????? idmap_ldb:use rfc2307 = yes ??????? ldap server require strong auth = No # Logs and events ??????? eventlog list = Security ??????? log level = 3 ??????? log file = /var/log/samba/pdc.%T.log ??????? max log size = 1000000 [sysvol] ??????? path = /usr/local/samba/var/locks/sysvol ??????? read only = No [netlogon] ??????? path = /usr/local/samba/var/locks/sysvol/exza.com/scripts ??????? read only = No -------------------------------------------------------------------------------------------------- Thanks & regards, Anantha Raghava Do not print this e-mail unless required.
