The only thing you need to watch out for when using doubletake, is that your servers in your production environment and your servers in your offsite location have to be on the same subnet for failover. So in other words, if your production network is a class c 192.168.1.x network, your offsite location has to be 192.168.1.x, otherwise doubletake cant failover a server thats on a different subnet.

If you are using third party software to do the data replication then you setup the server as per their instructions. Almost certainly it will not involve DR installation.

Hi,<br />
<br />
We're using Doubletake to failover a 2003 server running Ex2003 OWA &nbsp;to a remote site (different subnet) for DR. How do i get this to work so that the URL htttps://webmail.abc.com redirects to the secondary site when it can't see the primary site. I know we'll have to do some changes for Firewalls and A records, want to know what exactly.<br />
<br />
Thanks
