ForestPrep and DomainPrep with Exchange 2003

The process for checking whether ForestPrep and DomainPrep have been completed successfully has changed for Exchange 2003. Instead of running the ADSI Edit snap-in and Policytest.exe utility as is required for Exchange 2000, there's a new tool called OrgPrepCheck for Exchange 2003. This deployment tool can be found on the Exchange 2003 CD, or over on the Exchange 2003 Tools and Updates page. This Technet article explains what you need to do.
