My PC is in domain A, I need to manage an exchange 2007 server in domain B, When I install the admin tools it complains that domain A has not been preped for exchange 2007. In the old exchange 2003 model you could install run Active Directory Users and Computers from one domain, or even on a non domain PCand connect it to another domain(even without any domain trusts) to manage users, but we seem to have lost this ability with exchange 2007. Is there any way around this? thanks, Jason
