Ok, a company I manage IT for has 2 domains, all Windows shop, in two separate locations. One is in Washington state, where all the users are. In the office there are 1 domain controller for user's desktop logins and Active Directory, 1 backup, several in house application servers, file servers, and nightly backups run to a file server.
In CA, in a data center, resides the other domain, which the user's Exchange and OWA accounts run off of. Also has a main domain controller and a backup. This domain location has the web server in a DMZ, and also a Citrix connection from WA to a server here in CA.
The two domain names are different. How would I go about merging them? I don't know where to begin. The usernames are different for the same users on the domains. What would you suggest?
Some things to consider are many of the user's email/Exchange account names are different from their desktop login. I'd like to keep it this way after the domain merger. Both domains have different ISP's and firewalls of course.
On a side note, I also plan to upgrade the domain controllers to Windows Server 2008 from 2003. Only the CA side will need to purchase a physical server capable enough to run 2008.
