W2003 Server Bulk import users/passwords

I have an FTP server in a DMZ running on W2003 Server and using IIS. We have 80-odd sites and local users, and I want to put a second server in to mirror the first but in a different geographic location. I can bulk export/import the user accounts, but does that include passwords? HAving to re-set 80 or so user accounts doesn't sound like much fun! Can't use AD, as the DMZ is fully locked down so local users only.
