remembering mapped drives passwords in win2000

hi
can anyone pelase let me know how to make windows2000 system to remember the mapped drives password.
I mapped few network drives, and selected the option of persistant i.e reconnect at logon. but this doesn't remember the password. and at system logon it prompts the password again. is there anyway to make system to remember password
and not to show this dialog or anyway to not to show this dialog box.
I dont need solution like, disconnect drives, so that it wont ask again and
select the option that Dont restore connections at logon...

thanking you

regards
praveen
