Synology Secondary domain controller

Hello,
Thank you for doing the domain controller training video - it was well worth it. I have a question about secondary domain controller.

I have DS1522+ - I setup first one (DC1) as primary domain controller, created users, groups and shares with GPO and joined computer to domain - everything works great.

Since it is only domain controller, I wanted a failover so I added a secondary domain controller on another DS1522+ (DC2). Everything works good, sync and test all passed.

I wanted to test failover, so I unplugged DC1 from the network, changed the dns on the computer to point to DC2 and tried to login - it took a long time to login and after login - I do not have access to shares (the shares on a different NAS). I thought secondary domain was supposed to work -

Any help would be appreciated,.

You need to make sure DNS is running on that box and on your DHCP server hand the second Synology out as DNS 2.

Thank you - tested with updated DNS - it works.
