Microsoft ADMT (Active Directory Migration Tool) is a free entry level product which helps probably enough. All steps are detailed in the ADMT doc, download from the website.

However your requirement 1) will be very difficult. Better first test out everything on a replica of your environment (backup made by tape or imaging tools) on a diffrerent server. And even then, after all tests, SOME downtime (a few hours depending on all settings and the number of user accounts) will be unavoidable. Real 99.999% availability, even during upgrades, requires a cluster of servers both on NT and on W2K.


However when the server role is workstation authentication (not IIS or so), with a number of tricks and reshuffling of PDC/BDC roles you can minimise the downtime for workstations...

1. Sorry there is not way to do this unless you are setting up a new server to replace the old one! An upgrade of the current server WILL require it to reboot! There is no way around that.
Also the upgrade will stop all services from running, no way around that either.

2. Yes it will retain all users name and info.
