I am in a position where I need to upgrade me Exchange quickly, but can't upgrade my SBS 2000 server. A consultant I'm talking to tells me that we can install Exchange 2007 on my existing SBS 2000 domain and use it instead. He says it will work as long as we add a DC to the domain that is running Server 2003 and is the Global Catalog server. I know that you can add additional DC's to an SBS domain, but I always thought that the SBS box had to hold all the FSMO roles. Is what he is saying true?
