-------------------------------------------------------No - you can't modify
TTL for individual records.
Since the only time this needs to be modified is during failover or
failback, it's a simple matter to clear the local machine DNS cache (as
you've done).
General policy: don't make system-level changes for one-off situations.

Subject: [ExchangeList] Can we change the TTL from one hour to say 10
minutes.
Hi,
I am having Exchange 2003 FE/BE setup. And in my testing I found that FE
talk to BE using DNS. Now I am changing my backend server IP and also
update it in DNS records. I did flushdns on FE and its successfully
talking to BE on new IP.
I found the default TTL is one hour. Can I manipulate TTL entry for
Exchange record to say 10 minutes?
I am doing this some my DR testing.
Thanks,
Manjeet
