A Bridge Head Server is a Domain Controller in each site. Which is used,as a contact point to receive and replication of data between sites.
For Intersite replication, KCC designates one of the Domain Controller as a Bridge Head Server.In case the server is down KCC designates another one from Domain controller.
Let’s assume that, we have two sites US and China. And each site has 3 domain controllers.
Among three on each site, one domain controller acts as Bridgehead server which receives the replication data from other site and then it replicates to the other two DC’s within the same site.
You can move the servers from one site to other by just right clicking on the server and select which site it needs to move.
We can use the repadmin /showrepl command to verify successful replication to a specific domain controller.
To verify successful replication to a domain controller
Open a Command Prompt as an administrator:
On the Start menu→ right-click Command Prompt→ then click Run as administrator.
If the User Account Control dialog box appears, provide Domain Admins credentials, if required, and then click “yes” to Continue.
At the command prompt, type the following command, and then press ENTER.
repadmin /showrepl <servername> /u:<domainname>\<username> /pw:*
Under site expand server name → right click on NTDS Settings → you will find the replication options
KCC is a service of active directory. KCC service is responsible for intimating, or updating the changes made either in DC or ADC.
