configuring/installing Exchange 2003 using Double-take for failover

I am in the process of setting up a exchange high availability solution using double-take so i can learn how this works.

i currently have:
a DC called DC1 (domain.local is the domain)
Exchange 2003 called Exch1 (source exchange server)

i have another server with server 2003 installed which is not a member of the domain.local AD. (this will be the target exch server)

i am confused what to do next and how to get this working like we would in a productive enviornment, an i cannot find a good guide what do do to get this working in best practice.

i understand this:
I cannot join the target server to the domain using the same exchange server name
i cannot join another exchange server to the exchange organisation within the forest with the same name

i am confused what to do to the source and target servers to get the working properly as i cant just install exchange on the target with the same name to the existing org.

please can any one advise what my next steps are to configuring a standby target from my source live exch1 server using double-take.

thanks

hey thanks for that! i have been looking for something like this all day!

my confusion is:

if the target server is another exchange server in the exchange organisation e.g. exch2. then how can the databases in exch1 storage groups mount in the exch2 stand by storage groups?

i thought that a database can only mount if the organisation, servername, storage group and database name where the same?

hi there, thanks for every thing i got the eval of DT working.

your link helped me, but this may be for an older version as it requires exchfailover.exe.

what i did was

deploy a DC called DC1
installed the double take application manager (to do manual failover the app manager cant be on the source node)

Deploy a exchange 2003 server (EXCH1) with sp2, install double take and the double take application manager

Deploy the secondExchange 2003 server (EXCH2), install SP2, install double take and double take application manager.

once this was done, on DC1 i run the DT application manager and went through the wizard for exchange.

then tested, all works a treat.

thanks

Great to see you're using DT!  Looks like you have everything set up, but reach out to us if you run into any issues.

For everyone else:
In this scenario, you would create a new Exchange 2003 server in the same domain or a child domain, using a unique name and the default configuration - unless you'd like to change things like routing groups, etc.  Just make sure you have the same logical volumes (C: D: E:, etc) on both sides, though the size and physical disks may be different.

Run the DTAM wizard (part of the DT package) and you'll be all set.

And of course, reach out to support if you run into trouble!
