I have been reading the Microsoft documentation about how the replication works in windows 2003.
I Know that in Windows 2003 replication topology KCC is able to select the bridgehead server from
a prefered list and so, when the ISTG creates the intersite replication conections, the bridgehead from
this list are ramdonly selected.
Microsoft talk about if the servers in the list are not available then the replication for the
directory parition will not occour.
I have a question. If the server in the list are not availble or KCC detects some problem with these
is not the KCC able to select other Domain controller in the site which are not included in the
prefered bridgehead list ?
Is dangerous to select only one domain controller in the prefered bridgehead list ?
This is because in my Datacenter (hub) are only two domain controllers and one of them is the PDC emulator that
at the same time Microsoft recomends to be not included in the prefered bridgehead list.
Then if I have only one prefered domain controller this is a risk.
is it better does not select any prefered domain controller and so the KCC select one of them ?
is it better to select both domain controllers (also the pdc emulator) to be included in the prefered list
and in this way the initial load balancing configured by the KCC create the connections using both Bridgeheads ?
