Subject: constraining hydrogen bonds

Dear amber users,
   I am having a doubt regarding the usage of ntc=2, which will constrain
all bonds involving hydrogen atoms in md input.Is it true that if i
use this it will also constrain initial solute,solvent hydrogen bonds?
Is it that if i want to restrain all WC hydrogen bonds of DNA i should
specify the group seperately ?
Thank u very much for any help.
regrds,
madhu
