AD sites and subnets define your replication topology and also drive authentication traffic towards specific DC(s).

that is a good document but i am one thing is missing how to move member servers or computers to another site.i want to move my hub server to next site.
Mike KlineCommented:
domain controllers are what you see in sites and services; for member servers and computers the IP address is what is used to determine the site they are in.

You associate a subnet or subnets to sites.

So for example if you have 10.10.x.x  for the HQ site and 192.x.x.x for a remote site.  If a server gets moved from the 10.10 subnet to the new subnet then it would use the DC in that site because of the associated subnet.


Hi Yogesh,

As the Exchange HUB server reads the topology form Sites and Services, you can easily move the HUB server to the subnet of the site where you want to place it. But it will not show your HUB server in sites and services as you are able to see DC's in sites and services.

And more over when you move out of Exchange 2003 and come to Exchange 2007 and 2010, the Bridgehead server concept is removed. So it will have its connector configured to connect the HUB server in the other subnet. Or else you will be able to configure the connectors in EMC to route mails.

Hope this url will help you to make your task successful.
Move your HUB server to different site (Physical Site) and configure its NIC cards based on the IP address of that Site. And HUB will read the Sites and services to have its topology, if you have multiple domains then you would need to go through changes in Organization level Send connector.
