Hi Adnan, Your steps look correct. There are no ?secondary? or ?primary? DCs. All equal except for FSMO roles. http://samba.bigbird.es/doku.php?id=samba:fsmo-roles You do not need to back up sysvol or idmap as they should be already synced with other DCs. http://samba.bigbird.es/doku.php?id=samba:sync-sysvol http://samba.bigbird.es/doku.php?id=samba:sync-idmap.ldb Regards, LP On 28 Apr 2025

I'm new to AD and Samba but we have been running 1 Samba AD DC on our network for a year now, without trouble. We have 2 sites, separated by a street and linked together with a site to site L2 VPN (EoIP on MikroTik). DC1 on site 1 (the currently running) and we are trying to run a 2nd DC (DC2 and DC4) on the 2nd site. idmap.ldb and sysvol are synchronized, `samba-tool drs showrepl` shows

About a week and half ago I upgraded from 4.0.12 to 4.9.6. Overall, things are functioning. However, I have come across several strange behaviors and wandered if anyone else has noticed similar behavior on 4.9.6 or has any suggestions of what might be occurring. As background information, I have 3 DCs (dc3, dc4 and dc5) -- all running the same version (4.9.6) and all have the same configuration;

Hello, dc3 = principal DC dc4 = secondary DC I had this problem last month after updating samba to version 4.10.x. and also the schema from 45 to 69. But it looked like it had been corrected. Today I noticed that on dc4 there are computers that are not on dc3. I updated: 4.7.x to 4.8.x 4.8.x to 4.9.x and only after that I upgrade to 4.10.x version. When I run these commands: samba-tool

Hai,   Now, differences is fine, but can you see if one of the 2 servers is correct, and for that it might be handy to share the output.   You can push the good DB to the other DC. ( a forced replication )   And i can understand why you upgrade ...  Did you see :    samba-tool domain schemaupgrade --help Usage: samba-tool domain schemaupgrade [options] Domain schema upgrading Options:   -h,

im on phone, had a quick small look at the dc3 output. is your time in sync, it looks like a 3 - 10 min different. gr.

hi! Query, I have 3 DCs, in each of the servers should have configured the other two DCs in the resolv.conf? or with only the primary is enough? Maybe that's my problem that does not replicate the dc3 with the dc2 thanks to all!

I dont understand whats the question here. But what i can say about the resolv.conf settings if you have multiple dc's. You have to think in 2 DNS resolving settings. 1) on the server as client resolving ( resolv.conf ) 2) clients resolving ( DNS Services ) The difference explained. If i do : ping hostname this is a server which is doing a client dns request through resolve.conf

Hello James, Thanks for your quick response. Find attached smb.conf file from DC1 and DC2. Also attached the screen shot of the event viewer from the workstation. At the moment, we have brought down the DC3 and DC4 in another location and observed that DC2 is unable to replicate get the information from DC1 or send the information to DC1. It appears replication is working in background but

Hi, String of peculiar behavior continues... Samba Version 4.7.5, Bind Version 9.8 No. of Samba-AD-DC Servers : 4 (dc1, dc2, dc3 & dc4). All FSMO roles are on dc1. All the while all things were perfect. Yesterday, due to some reason, the BIND Service on dc2 stopped. This resulted in none of the other domain controllers could resolve the names. On dc2, only named service was stopped but

What do you see/get when you run: dig NS $(hostname -d) With 2 dc's you should see 2 records. In the past this was a bug at samba joins so only 1 NS record existed. Worth to have a look at. And adding this to /etc/resolv.conf: options timeout:2 options attempts:3 options rotate Also might help. Greetz, Louis > -----Oorspronkelijk bericht----- > Van: samba

Hello, I have implemented Samba as Active Directory Domain Controller with Version 4.6.3 on CentOS 7.3, el-514. We have 4 domain controllers named as DC1, DC2, DC3 and DC4. DC1 & 2 are in one location and DC3 & 4 are in a different location. DNS is SAMBA INTERNAL. All 4 servers are properly synchronizing and even GPO updates are working properly with rsync process. However, off late
