If you are sure you need two forests, they cannot share a common root name. Two forests, by definition, do not share security or contiguous namespace. Maybe you mean two trees in a single forest? Then you have different namespaces for each tree. How about adm.harper.edu and lab.harper.edu as domain names? If you "want Active Directory to manage both areas," why not use a single domain with separate OUs? -----Original Message----- From: Matt Fowler [mailto:mfowler@xxxxxxxxxxxxxxxxx] Sent: Tuesday, November 11, 2003 2:35 PM To: windows2000@xxxxxxxxxxxxx Subject: [windows2000] Multiple AD, 1 DNS domain name We are an educational institution that is considering a physical zoning of Lab's and Administrative domains. We want Active Directory to manage both areas. I understand we need to AD implementations and thus 2 forests. But, can they both have the same root DNS domain name (ie. xxxx.edu)? Or, do they need different DNS domain names (ie. xxxxadm.edu and xxxxlab.edu)? BTW: this could be either Windows 2000 or 2003. Thanks for any input.
