importing/exporting user data across all computers in network? HEL

Hi, there are 40 or so computers linked up over a LAN with about 50 users in
total. Now I've set up 1 computer in the network so that all user profiles
are on, all microsoft exchange mail's are set up so people can check email,
that macros are enabled and the certificate is installed, and that the
internet is set to a particular home page. Basically is there any way I can
save these settings and install them into the other 39 computers in the
network? Currently I'm having to go to a particular pc I want to setup, add
all the users and log into the pc as every different user, then set up the
email exchange server settings for that particular person and macros and so
on. 40 computers x 50 users = a very long time! Any help is greatly
appreciated. thanks
