which has implemented Active Direcotory 2008 (adcorp.local) and how approximately 10,000 objects (users, computer, printers) in the Active Directory. The reason for this presentation is ADcorp is pursuing acquiring another organization called GoodPurchase with an existing Active Directory 2003 domain (gdpurchase.local) with 5,000 objects. In your presentation, you are to present how ADcorp will integrate the organization under one forest, how accounts between the domain will work, functional forest level and domain levels, GPOs, etc. Use what you have learned in this course to demonstrate the ability to bring the two organizations.
