Sorry Paully, I thought i already replied it. The configs look good. Did a look back in time.. And Ahh.. Now this i missed. * yesterday, we changed the IP addresses of our DCs and the Wiki page did not mention (IMHO) 2 critical things... ... So you even missed more. Review all DNS entries for the problem DC and review your AD again. rgrep /etc and /var for all the old ip numbers and/or

Can you run the debug script, that might give me more info. https://github.com/thctlo/samba4/raw/master/samba-collect-debug-info.sh Anonimze where needed.

Hello Samba Mailing List, Just to be clear, I am using Ubuntu Server 18.04.4 LTS running Samba 4.7.6 on both DCs. Is this the Samba version I should be using for this

Hello Samba List, I have 2 problems with dns - seeing the child entries and a zone with an extra octet. First... I have created a /16 reverse zone as per the wiki page (https://wiki.samba.org/index.php/DNS_Administration#To_create_a_.2F24_reverse_zone)... $ samba-tool dns zonecreate dc3 130.130.in-addr.arpa $ samba-tool dns zonelist --reverse dc3 pszZoneName :

For some reason, the provision picked up 2 network IP addresses in my VM. Snipped output below... root at dc1.example.com ~ $ (screen) samba-tool dns serverinfo dc1 dwVersion : 0xece0205 fBootMethod : DNS_BOOT_METHOD_DIRECTORY fAdminConfigured : FALSE fAllowUpdate : TRUE fDsAvailable : TRUE

Hi Folks If I have 2 x Samba4 AD DCs, a primary and secondary, am I correct in assuming that if I add a Windows Client to the DOMAIN it should eventually replicate to the secondary DC? Paully

All i can think of whats left is : https://support.microsoft.com/en-us/help/929852/guidance-for-configuring-ipv6-in-windows-for-advanced-users Change the prio of the IP in windows networking. See if that helps/works, so ipv4 before

Guys, what i noticed. Look at this. Refused- 1/3/0 (Class 254) ( /24 ) Paully used /16 update 1/3/1 (Class 254) CNAME V-RDS02.mydomain.com CNAME ? And, if he uses in his example samba-tool dns add dc3 mydomain.com V-RDS02 A 130.130.0.252 A record was used. Is resolv.conf checked and it is sure in pointing to the correct DNS of the AD first? addresses: -

Hello, When I run the following command... $ samba-tool dns add dc3 mydomain.com V-INT A 130.130.0.202 ...I get the following error... ERROR(runtime): uncaught exception - (9711, 'WERR_DNS_ERROR_RECORD_ALREADY_EXISTS') File "/usr/lib/python2.7/dist-packages/samba/netcmd/__init__.py", line 176, in _run return self.run(*args, **kwargs) File

My reverse zones have PTR records. Though I don't have NS records for all of my DC's. I guess that needs to be manually created. Also, you don't have any CNAMES or domain overrides pointing to a single DC? Perhaps Bind is pointing to another internal DNS server, and then to a public DNS? ---- Here's a way to test failover from a Windows client: You can switch logon servers

Is DC4 listed in in an A record for your mycompany.com? Do logs show that it's answering requests during the course of a normal workday? If so ... time to simulate DC3 failure, I guess.

Hi Paully I can help with showing the "subgroup" 0: instead of @ use 0 samba-tool dns query dc3 130.130.in-addr.arpa 0 ALL the additional 0 might be a bug in 4.7, which is end of life; I would suggest to upgrade first......but Rowland will know more about it probably. br Mani On 03.11.2020 11:24, Paul Littlefield via samba wrote: > Hello Samba List, > > I have 2 problems
