Understanding IFM (Install From Meadia)
Install From Media:
Installing from media involves creating installation media a specialized backup of Active Directory that can be used by the Active Directory Domain Services Installation Wizard as a data source for on a new DC. Then the new DC will replicate only updates from another writable DC.
For example there is a Main DC located in Head Office (Delhi) and you want to deploy a new DC in Branch Office (Lucknow) in this forest bandwidth might be issue. So IFM can be use as a solution for it.
You can reduce the amount of replication required to create a domain controller by using the IFM option. IFM requires that you provide installation media, which is actually a backup of Active Directory.
Exercise: Create Installation Media
1. Log on to SERVER1 as Administrator.
2. Open a command prompt.
3. Type ntdsutil and press Enter.
4. Type activate instance ntds and press Enter.
5. Type ifm and press Enter.
6. Type ? and press Enter to list the commands available in IFM mode.
7. Type create sysvol full c:\IFM and press Enter.
8. Quit

The installation media files are copied to C:\Ifm.
Now this file can be used to install New DC in existing Forest.
