Installing Windows Server 2008 (64bit) Domain Controller in an existing Windows Server 2003 (32bit) domain

In this post, I will show us how to install a new Windows Server 2008 R2 (64bit) domain controller in an existing Windows Server 2003 domain (32bit). Sorry that I am not able to provide any screenshots at this point in time but if you simply follow the steps, you won’t miss it 🙂 If this domain controller is the first Windows Server 2008 R2 domain controller in the forest, you must prepare the forest for Windows Server 2008 R2 by extending the schema (that is, by running adprep /forestprep) on the schema operations master if this has not already been done.
