I created 3 remote sites and subnets assigned to those sites. Remote DC's have been joined with the " --site" option. I even tried to setup Site Links, but it doesn't help. Here is my topology Main Site: DC1 DC2 => well replicated from DC1 DC3 => well replicated from DC1 Remote_Site_1 DC4 => tries to replicate from DC2, but fails with WERR_FILE_NOT_FOUND error (even manually with samba-tool drs replicate DC4 DC1 DC=mydomain,DC=lan) Remote_Site_2 DC5 => well replicated from DC1 Remote_Site_3 DC6 => well replicated from DC1, but sometimes fails trying to replicate from DC3... I tried demoted DC4 several times and rejoined it, whithout success. Each time it fails with ths machine (i checked network and dns settings, nothing's wrong) So from what i see "drs showrepl" shows me that sometimes a remote DC tries to DC1, sometimes not, and i would like to control it.

I don't know what's going wrong with DC4, but it's the only DC i cannot sync manually from DC1. I purged every single drop of samba on it an re installed it from scratch, and and it still does the same for it (even with --remove-other-dead-server demotion and dbcheck on DC1). I guess I'm gonna try to install another machine as I don't know what to do here.
