I need your expert help in designing a network which has failover solution in terms of disaster and recovery. My company wants me to come up with some kind of solution in which we can use two or more server as PDC and BDC so that in the even of our main server goes down for some unexpected reasons the users wont get effected and they carry on doing there work as per normal or with minimum disturbance and when the PDC comes back it sync the data with any changes from the BDC. I know this concept is very old in the age of NT 4 I searched on googl but cant find anything which can provide a solution to my problem.
Please guys help me tell me what are my options.
Hope to hear from you guys soon.
