I'm looking for some procedures to migrate users from a stand-alone Windows NT 4 server to a stand-alone Windows 2000 Server.

Any insight or solutions would be appreciated

Thanks

if it is truely a stand alone. preform a complete backup and run the upgrade. There really isn't anything special . just remember to stop all the sevices like wins and Spoller...
that is the only catch.

Thanks, but I'm trying to get the SAM database and user accounts from this machine to a tottally new, Win2K server, on which the method of a backup-restore-upgrade solution will not work :(

you can use a third party migration software after you set the win2k server, and also you can use the ADMIT it can backup your users accounts the thing it will have an old SID as history and create a new one, and you have to tell your users to create a new password

ADMT works.

Safest proceedue is usually to add an NT BDC to your domain, promote it to a PDC. Then upgrade this new machine to W2K.

You can now build your new server, join it to the W2K domain you just made. Finally, transfer all operations roles to the new server and demote the the temporary one.

If anything goes wrong, you still have the old server intact.

You probably get a cleaner setup with better default permissions if your final server is not an upgraded NT4 PDC.

I believe you mean Stand-alone and not domain, it is just a stand alone computer with no Domain controller. This is one of the reasons you need a domain controller, it is possible using backup and restore to accomplish this (restoring to a computer with different hardware), and then upgrade to windows 2000. However this is a lot of trouble to do. I would reccomend setting up the new Windows 2000 Server, run DCPROMO on the new server, setup Active Directory. Then copy all the files (data, not system) from the old computer.
If however this is a WinNT PDC:
1. Install WinNT on the new machine, as BDC.
2. Promote new machine to PDC.
3. Upgrade new machine to Windows 2000.
4. Run DCPROMO.
