Installation and Upgrades / Reprovisioning stopped working between two Zentyal servers

« on: May 12, 2015, 08:07:50 am »

So I have two zentyal servers, one as PDC and one as additional DC. It was working perfectly until last week. Now if I add a new computer to the domain it appears on one of our DCs but not on the other one. Same with users, if I deactivate one it doesn't get deactivated on the other DC. I was waiting more than a day to make sure it's not syncing (I heard it takes some time to sync but not one day).
If I execute 'sudo samba-tool drs showrepl' command on my PDC this is what I see:

Code: [Select]

DC=ForestDnsZones,DC=mydomain,DC=lan
        Default-First-Site-Name\SDC via RPC
                DSA object GUID: 0a989f75-b8b8-4ae4-a6d3-b1a66fa1f895
                Last attempt @ Thu Apr 30 07:19:53 2015 CEST was successful
                0 consecutive failure(s).
                Last success @ Thu Apr 30 07:19:53 2015 CEST

DC=DomainDnsZones,DC=mydomain,DC=lan
        Default-First-Site-Name\SDC via RPC
                DSA object GUID: 0a989f75-b8b8-4ae4-a6d3-b1a66fa1f895
                Last attempt @ Wed May  6 07:48:41 2015 CEST was successful
                0 consecutive failure(s).
                Last success @ Wed May  6 07:48:41 2015 CEST

As you can see, the last attempt was on Apr 30. If I execute the same command on the secondary domain controller it says that the last attempt was about 5 minutes before executing the command. And there are other errors like WERR_SEM_TIMEOUT, WERR_WRITE_FAULT in the output.

Zentyal version is 3.4 on both servers, but we can't upgrade to the newest release for different reasons. Any help would be appreciated.

Edit 1:
Executing the following command
samba-tool drs replicate primary secondary CN=Configuration,DC=mydomain,DC=lan
returns this:

Code: [Select]

ERROR(<class 'samba.drs_utils.drsException'>): DsReplicaSync failed - drsException: DsReplicaSync failed (-1073610723, 'NT_STATUS_RPC_PROTOCOL_ERROR')

    raise drsException("DsReplicaSync failed %s" % estr)

Installation and Upgrades / Two Zentyal servers sysvol problem

« on: September 02, 2014, 02:34:27 pm »

Hello guys!

We got two Zentyal servers in the same domain, one of them acts as a PDC of course and the other acts as a secondary (or additional) domain controller.
Everything works quite fine except the sysvol share. If I open the \\mydomain\sysvol\ share on my computer I can see the Policies and scripts folders but when I open it on another PC the Policies dir is missing and the scripts folder is empty. I figured it out that the empty sysvol share belongs to my additional DC and that it is caused by DFS. On my computer if I open the properties of \\mydomain\sysvol\mydomain there's only one path is in the DFS section but if I open it on a freshly installed computer it contains the sysvol share of both DCs and the secondary share is set as active.
Is there any way to get rid of this DFS root or set my primary server as active on all computers remotely?

Thanks in advance!
