environment that includes Microsoft Exchange Server 5.5 computers and Microsoft Exchange 2000
Server computers in a single Exchange organization.
The company has deployed a single Microsoft Active Directory forest. All domain controllers run
Microsoft Windows Server 2003.
The company has 5,000 employees. The company decides to migrate all the mail servers to a Microsoft
Exchange Server 2007 environment.

the new organization.

Run the adprep /forestprep command from the Windows Server 2003 installation CD on the server
configured as the Schema Master server.
