[ActiveDir] 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
