otherwise error message "Could not retrieve time from AD server other.ip.add.ress via NTP" may occur.

Domain Controller and File Sharing = 6.0.1
Server role = Additional domain controller
Samba -V = Version 4.7.6-Ubuntu

Running a (Windows 2008 R2) PDC with Routing and RAS enabled, including "Enabling broadcast name conversion" might trigger "Could not retrieve time from AD server 192.168.1.2 via NTP", where "Domain DNS server IP" was specified 192.168.1.1.

It would already be nice when Zentyal would try to retrieve the NTP time only from the supplied IP of the PDC, and not query anyother IP's that are assigned to internal interfaces for VPN servers running on top of that machine.

Workaround
For the time being I will disable the related setting: Routing and RAS > Server > Properties > IPv4 > "Enabling broadcast name conversion" and manually remove the IPv4 address from DNS.
