Restoring DUN settings after cloning

I am upgrading from win98 to win2000. I plan to use Norton Ghost. Each computer has specific DUN settings. Is there a way to save these settings so I only need to restore them after cloning? I work at a telecommuting center where I have about 25 computers and each has different remote control software and DUN settings (some have many DUN settings for different users), not to mention all the idividual files. I’d like to ghost the machines over the network (all at one time) and avoid having to set up all the individual and unique settings for each user all over again. Maybe there is no way around this, but any input would greatly appreciated. Thank you.
