I am building a new network using Dell 2900 servers. My Exchange server is 64bit running Windows Server 2003 R2 and my new DC/AD box is x32 running Windows Server 2003 R2. I am attempting to install Exchange 2007 and am running the Best Practice Analyzer. It is scanning my Domain and says No Exchange organization container found in domain. Looking this up, it says to run domainprep on the DC. However, since my media is x64, it won't run on my x32 box. What do I do?
