Fabrikam has a single domain.
In order to prepare a domain, run the following command from an elevated command prompt after browsing to the Exchange 2013 DVD/ISO.
Setup.exe /PrepareDomain /IAcceptExchangeServerLicenseTerms
If you have a single domain environment, you don't have to prepare the domain as the local domain is prepared for 2013 as part of preparing the AD. But, if you have a multi-domain environment, all other domains (except the one on which the AD was prepared) has to be ready for 2013.
You can prepare all the domains in one go by running the command below.
Setup.exe /PrepareAllDomains /IAcceptExchangeServerLicenseTerms (you will need Enterprise Admin rights).
