I do have clustering setup and I'm using a remote
location. I have implemented Double Take to image our
Exchange data to a remote server. When our corp exchange
cluster is down the remote cluster will take over but
webmail will still be down unless I create the A record
manually and wait a period of time untill the A record is
updated with the new IP adress.

Thank you,

Juan
