As an IT Administrator, what happens when you get instruction from your superior that you need to deploy a new Domain Controller in a remote site, but yourntds.dit file is over Gigabytes of size, and your WAN is very slow?
So, to solve this issue, we can always deployed the additional Domain Controller using the install from media (IFM) method.
Using the IFM method, you can dramatically reduce the amount of replication traffic that is introduced during the installation of an additional DC. Only objects that were modified, added, or deleted since the installation media was created will be replicated.
This is just a simple step but workable in my LAB environment.
For this demo, i will be using ntdsutil.exe and will continue will normal domain installation.
1 – On your DC server (OSI-ADDS01), open CMD and type ntdsutil.exe, next typeActivate instance ntds then enter.
— next, type IFM and enter
— next, type create sysvol full c:\ifm and enter
2 – If the process successfully, you will see information in the cmd stated that “IFM media created successfully in c:\ifm”
3 – Next, in your ADDS Server, open explorer and browse to ifm folder to verify the existence of the folder.
4 – Next, make sure you share the IFM folder so that the other remote server can access to ADDS server and copy IFM server from the ADDS Server to remote side server…
5 – Once you successfully copy the IFM folder into remote site server (in my demo the server name is OSI-ADDS-IFM), on the server open Server Manager and click on the exclamation mark, and then click Promote this server to a domain controller…
6 – on the Deployment Configuration, click Add a domain controller to an existing domain, and then in the Domain box, key in your domain name and click next…
7 – Next, on the Domain Controller Options, make sure Domain Name System (DNS) ans Global Catalog (GC) is selected and then key in your password and proceed with Next…
8 – Continue Next on t he DNS Options…
9 – On the Additional Options, click Install from Media and browse for the ifm folder that you copy from the ADDS primary server… and then click verify button to confirm.. and then click next…
10 – On the Path click next to continue…
11 – On the Review Options click Next…
12 – On the last step, check on the Remote Side Server (OSI-ADDS-IFM) to confirm that all the Domain Controller information has been deploy successfully.
