Hello. I am in the process of planning a front-End / Back End scenario for our Exchange system. Currently, we are running Exchange 2000 Enterprise on a Windows 2000 advanced (non clustered) server. I have some questions that I was wondering if someone might be able to assist me with. 1. Which server machine, Front or Back, should be more powerful? 2. We currently have in production a "Webserver", which hosts our Website. Is it possible to make this machine also a Front End server? 3. Is it true an organization can have one front-End Server and several back end servers (for different organizations / domains)? We want to have two independent mail systems 4. How easy / difficult is it to migrate / move from our current structure of one Email server to Front-End / Back End 5. Has anybody had experience with Front-End / Back-End? Any feedback would be appreciated. Thanks for your time. Regards, Mark mbudman@xxxxxxxxxxxx
