I'm trying to install a new Windows 2008 forest in our existing corp network in preparation for a migration. Our existing corp network is Windows 2000, and the domain is ourcompany.com. I want to name the new 2008 network ourcompany.local. But dcpromo is telling me I can't because of a name conflict. Why is that? Isn't the .com and .local completely different? The ourcompany.local does not currently exist anywhere in the DNS server.
Any ideas how to get around this?
