Automatic connection to network

I have a windows xp that I just upgraded. I had a celeron computer, used PC mover and moved everything to my new duo double core with XP as well.

Previously I was able to access network programs (on a windows 2000 server) without a password, however, it now always prompts me. Obviously this setting change did not move over to my new system.....I don't remember how I did it last time.

and no, I don't see any little box to click that asks me to save this password for nexttime.

Thanks!
