When you have more than one active directory server on a windows domain they keep copies of the Active directory of the domain on each server. Should one active directory server fail the another on the domain can be told to take over roles.
Question --- Can It be like this for an Exchange Servers? I believe the answer is no but I need to ask to be positive. I believe you can not have more than one Exchange server on a domain and therefore there is no dynamic backup copy like this for exchange. correct?
