Hi all. I have few questions I would like to ask. I have main domain abcd.com and I created child domain headquartes.abcd.com. I also have exchange 2003 server setup in main abcd.com domain. I want my local LAN users log into headquarters domain and not to be able to get to upper level (main domain browsing). Here is the problem I am running into. My local users accounts setup in my main domain so they would have exchange email account but if they trying to login into child domain they cant because there is no name associated in child domain user account. Do I have to create identical user profiles/signon in main domain and child domain? Or is the any way I can set it up so the users will replicate from main domain trough the child domain and then I could set it up to what level they could go up? Or do I have to create users in my child domain for login and setup exchange server so it will pull users accounts from this child domain and associate with main domain? Next thing, I have few partitions setup on my exchange server, how do I assign separate partition for logs files, and for users mail boxes other partition, separate from exchange main partition and system partition? Next questions is, I couldn’t figure it out how to make exchange server assessable from web (site wont came up) I read all notes in here but still wont work. IIS is up and running port 80 OK. Also I need to install SQL server and I want this SQL server be available for both main and child domain, where should I install this server, can I install on childe domain server, I don’t wont to overload my main domain server, its already running a lot of tasks. Thank you.
