We have 3 offices in 3 different cities connected by a 10MB fibre link.
City A is the head office with 100 employees.
City B has about 30 employees.
City C has about 20 employess.
Currently, we have each office logging in to their own Server 2003 domain but all connecting/sharing a central Exchange 2003 server which is located in the head office.
My question are:
1. Is this an optimal AD configuration or should we have everyone logging on to one central domain?
2. How do we add some redundancy to our Exchange Server 2003? That is, having everyone from different cities share one central mail server makes me a little nervous.
Thanks very much.
