Samba4 turn off replication

Hi

(c1bcbaf3-c4d8-4329-9246-ad2effef3c99._msdcs.hh3.site) on port 135 - 
NT_STATUS_HOST_UNREACHABLE.

Just for convenience and to stop this stuff filling up the logs on a 
test lan whilst the other DC is down, is there any way I can temporarily 
turn off replication?

Something like
  samba-tool drs replicate off

Cheers,
