No, you can install the ADC and use an Exchange 5.5 server in a different domain to retrieve the site/org information which forms the basis of the CA that is created before you run forestprep. So:
1) install the ADC on one of the domain controllers (make sure you run the ADC with a user that has permissions on the 5.5 site) 2) run forestprep, on the schema master preferably. 3) wait until all the changes are replicated and then install e2k Darren. -----Original Message----- From: Rittenhouse, Cindy [mailto:[EMAIL PROTECTED]] Sent: 05 June 2002 15:11 To: [EMAIL PROTECTED] Subject: [ActiveDir] Forest Prep and ADC I am working in my test lab and I am unclear about the requirements for ForestPrep. I have an AD root domain and an NT domain. My AD root consists on 2 DCs only. DNS, DHCP, and WINS are in place. There is a trust between the domains. I have read that it is best to run ForestPrep at this point, but my Exchange 5.5 server (a W2K member server) is in the NT domain. I have documentation that says ADC must be installed in the Forest before I can run ForestPrep. Since the Exchange server is not located in the Forest/AD domain, do I need to install the ADC on one of these DCs. Will it allow me to join an existing Exchange 5.5 Organization in an NT domain. Do I need the ADC installed on the Exchange server before I Forest Prep the AD root domain. Thanks Cynthia Rittenhouse, MCSE, CCNA LAN Administrator County of Lancaster 900 E.
