This article describes how to copy domain objects from one domain to another by using the tools that are provided in the Microsoft Windows NT 4.0 Resource Kit Supplement.NOTE
: It is recommended that you test the steps that are described in this article in a test area before you use them in a production environment.
The Resource Kit tools are:
- The Addusers.exe tool can be used to import and export user and group accounts from one domain to another.
- The Rmtshare.exe tool can be used to remotely create or delete shares.
- The Scopy.exe tool can be used to copy NTFS file and folder permissions from one share to another. (This tool, however, does not copy share permissions.)
- The Permcopy.exe tool can be used to copy share permissions from one share to another.
- The Subinacl.exe tool can be used to obtain security information on files, registry keys, and services, and to transfer this information from user to user, from group to group, and from domain to domain.

To Migrate Users and Groups to Another Domain
- You can use the Addusers.exe tool to migrate users and groups to another domain. To transfer existing user and group accounts to a file, use the addusers \\computer_name|domain_name/d filename command, where "computer_name|domain_name" is the name of the primary domain controller (PDC) computer that contains the user and group information for the specified domain, and "filename" is the new file that contains the user and group account information.
When the user and group information is transferred to a file, the information is saved in a comma-delimited format.
This transfer of user account information does not save user account passwords or any security information to the file. When you use this transfer file to migrate users to another domain, all of the newly created user accounts have a blank password and, by default, all of the newly created users are required to change their passwords at their next logon sessions.
- To add the users and groups to the new domain, use the
addusers \\computer_name|domain_name/c filename
command, where "computer_name|domain_name" is the name of the PDC computer and the domain where the user accounts are created, and "filename" is the name of the comma-delimited transfer file that contains the user and group information.
NOTE: The Addusers.exe tool and additional documentation is included in the Windows NT 4.0 Resource Kit, Supplement 3. To view the other parameters that you can use with this tool, at a command prompt, type: addusers /?, and then press ENTER.

To Create Shares Remotely
To create or to delete shares on a remote server by using the Rmtshare.exe tool, use a command with the following syntax:
rmtshare \\server[\sharename[=path [/printer]]] [/grant [user[:perms ]]] [/remove user][/users:number] [/unlimited] [/remark:"text"] /delete
An explanation of the syntax of the preceding command is:
- The "\\server\sharename" syntax refers to both the server and the share that you can create, inspect, modify, or delete.
- The "/grant user:perms" syntax adds the name of a valid user or group on the server that have permissions, or changes the permissions of the user in an access control list. The valid permissions are: r=read, c=change (write), f=full, and n=none. You can type "read", but only the first character is used.
- The "/remove user" syntax removes the specific entry for a user. Then, that user inherits permissions (in contrast to "/grant user:none" that denies any access to the user).
- The "/users:number" syntax is the number of users that have privileges to the server and share.
- The "/delete" syntax deletes the share that are specified by the "\\server\sharename" syntax.
: If a sharename or path contains spaces, enclose either the sharename or path in quotes, for example: \\server\"with space"="c:\with space".

To Copy File and Share Permissions
Two tools are required to copy NTFS and share permissions: The Scopy.exe tool is used to copy NTFS file and folder permissions, and the Permcopy.exe tool is used to copy share permissions.
To copy files and folders, and retain their NTFS file and folder permissions, use the Scopy.exe tool and the scopy source destination/o /a /s
command, where "source" is the path to the source folder and "destination" is the path to the destination folder. The /o
option copies the owner security information, /a
copies the auditing information, and /s
includes all of the files in the subfolders.
The Scopy.exe tool cannot copy files to or from file systems that do not use security features, such as, file allocation table (FAT) and high-performance file system (HPFS). The Scopy.exe tool copies only NTFS file system security information. This tool cannot be used to copy share permissions.
To copy the share permissions from one share to another by using the Permcopy.exe tool, use the permcopy \\source_server\share_name \\destination_server\share_name
command, where "source_server\share_name" and "destination_server\share_name" are the universal naming convention (UNC) paths to the source and destination shares.NOTE
: You cannot use the Permcopy.exe tool to copy the permissions of an administrative share (sharename$, such as, C$ or IPC$). If you copy the permissions to an administrative share that is located on an x86-based computer, the Services.exe program can stop responding.
To Migrate Registry Keys, Services, and Other Objects
The Subinacl.exe tool can be used to obtain security information on files, directories, registry keys, and services, and to transfer this information from user to user, from group to group, and from domain to domain.
To migrate other domain objects by using the Subinacl.exe tool, use a command with the following syntax:
subinacl /object_type object_name /action=parameter /action=parameter
The object types that can be manipulated by the Subinacl.exe tool include:
- Registry keys and subkeys
- Kernel objects
The actions that can be performed on the preceding objects include:
- Change ownership
- Replace all access control entries in the object
- Change domain name of the object
- Migrate the object from one domain to another
To replace the security identifiers in all access control entries that
contain "Domain1\Sales" with those of "Domain2\Sales",
use the Subinacl.exe tool, and the following command:
