KB121618 - Saving Workstation Default User Profiles for a Domain

In order to save the default user profiles of a local system and make them available to the domain, use the User Profile Editor. It is available in Windows NT Advanced Server version 3.1, Windows NT Server version 3.5, and the Windows NT 3.1 Resource Kit. If you do not have any of these products, and you have a Windows NT workstation, you can save your default user profiles from a domain server.

In order to save a workstation's local default user profile and make it available as a domain user profile from a domain controller, the following procedure is recommended:

From the Windows NT server, create a domain user account for the Windows NT workstation and register the computer name on the domain.
From the Windows NT workstation, join the domain. When you have successfully joined the domain, log off of the computer.
From the Windows NT server, run the User Profile Editor and connect to the system root directory (C$) of the Windows NT workstation, using a domain administrator account name and password.
Make the workstation's default user profile available to the domain by saving the profile with a USR extension on the domain controller. Default user profiles are located in the %systemroot%\systems32\CONFIG (where %systemroot% is the root directory for Windows NT, usually WINNT) sub-directory, usually with the following format:

<First 5 characters of user name>000
Open the new USR file with the User Profile Editor Tool, permit the new Domain user to use this profile.
