copying the database one domain to another.. HELP

i got a new install of wordpress under a different domain. i saved a copy of the database through phpmyadmin. i dropped all the tables from the new install and imported the old database into the new… BUT when i log into the backend… it redirects me to the old domain..

is there something in the database thats doing this? i can browse the front page fine… its just when i click on any of the links or try login…

thanks for the help in advance
