Extend your Active Directory Schema

Since we are about to extend the Active Directory schema to make room for Exchange server Active Directory related entries, the command below shows you which server will get this update - it will be the schema master for your Active Directory infrastructure.

So, now we know which server will get the update to the schema master. Here is what you need to do to get this database extended for Exchange Server 2016.

• Access the Exchange2016.exe program that was made available to you on the S: drive under the NOM2 folder. I placed the ExchangeServer2016.exe into c:\setup\exchange on my EX01 server. This file actually contains the Exchange2016-x64 installation files, so you will have to execute it to extract the actual setup files.

• Run the Exchange2016-x64.exe to extract the setup files. Place the files into the ExchangeServer2016 as well.

• After the files are extracted, you can delete the ExchangeServer2016-x64.exe program to save disk space if you wish.
• We now need to access the setup file using PowerShell. Open PowerShell and navigate to the ExchangeServer directory that we just populated with setup files and type the command highlighted in the image below.

• If this process fails, then reboot and try again. A successful atempt will look like the image below.
