In this Tutorial we are going to test how the resume setup of Exchange Server 2013 works. In order to test it properly during the Exchange Server 2013 setup process we will be turning off the domain controller, and as we know the Active Directory is the foundation for Exchange Server.
In the image below we can see the error message where a Domain Controller is not available, by default a new Exchange Organization requires 15 steps and the issue occurred during the Step 8, which means that at this point the Steps 1 to 7 were completed successfully. After getting the error message, there is nothing that we can do, just click on Exit and solve the situation before trying again the installation process.
In our case, the solution was easy, we brought the domain controllers up, and we ran the setup.exe and the following page is displayed. The setup detects that the last attempt was not completed and it will retry the process, from the administrator side we just need to click on Next.
The setup will resume, and if we can notice that now we have only 8 steps left, and the reason is that the first 7 steps completed successfully are not part of this new version of the setup process.
So, now you know, if something goes South during the setup, we can always try to resume the operation by running again. Just make sure that you solve the error before trying it again.
