[Samba] Win Clients and DNS

[Viktor Trojanovic]

I have an AD with 1 Samba DC and 5 Windows 10 clients. The DC and the 
clients all have a fixed IPv4 address.

In the windows event viewer, I constantly see the following warning:

Event 8019, DNS Client Events
------------------------------------------
The system failed to register host (A or AAA) resource records (RRs) for 
network adapter with settings:

Adapter Name: {someGUID}
Host Name: Client-PC
Primary Domain Suffix: SAMDOM.COM
DNS Server list:
     192.168.0.1
Sent update to server: <?>
IP Addresses:
    192.168.0.15
------------------------------------------

Is it necessary to manually make some entries in DNS for the client 
machines? I didn't see anything about that in the Wiki.

I'm trying to figure out if this is connected to another problem I'm 
facing. A machine based GPO is not executed because "the file 
\\SAMDOM.COM\SysVol\[...]\gpt.ini from a domain controller could not be 
read", and as one of the possible reasons for the error, name resolution 
is mentioned. I can access the file just fine once I'm logged in so I 
really don't know what the issue is here.

Thanks,
Viktor
