We currently have a single Windows 2008 R2 Active Directory domain controller, and an Exchange 2010 server. We are in the process of adding a child domain on a second Active Directory server for an offsite office location for a subdivision of our company. The two locations will be connected via VPN.
Currently users (approx 20) exist on the root domain with Exchange accounts who will be moving to the new offsite company/location. We would like to be able to move these user accounts to the child domain while maintaining their existing Exchange mailboxes and email addresses (they will continue to share one Exchange server). Is this possible, and if so how would we do it?
It is being setup as a new child domain for the offsite location - the new location is an independent company (partially owned by the parent location/company) and they want an indepdent login domain. Ie. if the corp headquarters logs in with domain ACME\ (ACME.local) then the new office wants to login as FOOBAR\ (FOOBAR.ACME.local) and not ACME. The only shared resource will be the Exchange server (in root domain ACME).
FYI I followed the reasoning and process decribed here for creating an AD child domain: http://blog.pluralsight.com/server-2008-active-directory-adding-a-child-domain
Note: the remote office needs the ability for a local staff member to be able to reset users passwords for users in that office, but not in the parent company office.
***Thank you very much for the advice and sorry that I can't comment properly!!
