Hi,

i have 2 DC in Lan and 1 DC, over the wan link, at remote site, between a
firewall.

If i have a fat Wan Link. Can i ignore about creating a new 'site' for this
remote DC?
What i have done now is by creating the LAN & remote subnets and attached to
the 'default sites'. Can this method work?

Yes, this method will work.  It is recommended that you always define your
subnets and sites.  If your WAN pipe is considered fast, then the two
physical locations can reside in one logical site.  The important thing is
that you still define the subnets (which you have).  If you don't do this,
your event log and NETLOGON log will be full of messages regarding clients
using a DC because they don't have a site.

Hi Paul,

thanks for your valuable advice.
If says, i wanted to create another new site for my remote site(for 1 DC).
My objective is replication will only take place in the night for this remote
site.

How can i achieve this? Do i change the schedule in the 'defaultSiteLink' or
change the schedule in the "NTDS Settings" > "automatically generated" for
servers?

i only have 2 sites (remote and Lan). i don't need to create a new site
link, right?

steve

In this scenario you should create a new site object and then link the
necessary subnets to this site.  Then move the server object into this site.
When you create the site you will have to pick a site link object.  The
default is fine if you only have two sites.  You can then change the
schedule on the site link object.

Hi Paul,

yes i only have 2 sites, so If i change the schedule only at night on the
DefaultIPSiteLink will it affect the the LAN AD replication between the 2 lan
DCs?
For remote site, the transport was show as 'IP' instead of RPC, is this
correct?

The schedule will only effect Inter-site replication.  Intra-site
replication remains unaffected at either 5 minutes (2k) or 15 seconds (k3).

Hi,

When all 3 DCs in a same site, each of them have 2 replicate partners. But
after i moved DC3 to the remote site, this remote DC only have 1 replicate
partner(DC2).
DC2 have 2 partners and DC1 only have 1 partner(DC2).

is this normal? should every DC have 2 partners?

This is fine.  The connection objects are between the bridgehead servers at
each site.  All traffic is "routed" through these bridgehead servers
(high-level explanation ;-)

I understand brigehead servers are servers only handle replication. But in my
'site Link', i did not specify any server to be brigehead server in the "IP"
settings.

SO does it depends the KCC doing the auto calculation for each servers'
partners?

Yes, the KCCs/ ISTG will assign the role of bridgehead server to a server
and then generate the most optimum replication topology, utilising the
bridgehead servers.

As per Paul's comments but also consider other apps such as SMS and DFS etc.
They may require that you create additional sites, even though the link
speeds are LAN equivalent.

If you implement DFS for example, and have replicas in remote and LAN, you
may prefer that clients are always referred to the local replica and not go
over the WAN. This means separate sites are needed.

Food for thought,
neil
