Hi,

there is no firewall, all DCs are in the same subnet.

here ist the output of a test, you can see, the CNAME guid entries in
the _msdcs can be resolved on any DC: (DC1 and DC2 are the first and
second DCs, SAMBA3 was added at last.

ldbsearch -H /srv/samba/private/sam.ldb '(invocationId=*)' --cross-ncs
