SUMMARY
=======
Windows NT implements replication to maintain identical copies of specified
files and directories on different computers. Changes made to files on one
computer are automatically replicated to other computers configured to receive
the changes. Replication requires a Windows NT Advanced Server to serve as the
export server. The import server(s) can be other Windows NT Advanced Servers,
Windows NT workstations, or OS/2 LAN Manager version 2.x servers. The
information below provides detailed instructions to replicate information from
an export server to an import server.
MORE INFORMATION
================
Perform the following fourteen steps to configure the export server:
1. Run the User Manager from the Administrative Tools group.
2. Create a new account for replication (for example, REPL). Specify a password,
if desired. Remove the check from the "User must change password at next
logon" check box.
3. Choose OK. Then close User Manager.
4. Run the Control Panel and select Services.
5. Choose the Directory Replicator service and choose Startup. Change the
Startup Type from Manual to Automatic.
6. In the Log On As control, choose This Account. Then choose Add User. Select
the account created in step 2 above and choose Add.
7. Type the password for the replication account and choose OK. Control Panel
responds with a message such as "The account DOMAIN\REPL has been granted the
Log On As A Service right and added to the Replicator local group." (If this
message does not appear, use the User Manager to grant this right. In User
Manager, choose Policies, then choose User Rights, and choose Show Advanced
User Rights. Select Log On As a Service. If the replication account does not
appear in the Grant To box, click Add, then Show Users, highlight the
replication account, click Add, and click OK. The replication account should
appear in the Grant To box. Click OK.)
8. Choose OK to dismiss this message.
9. Run the Server Manager from the Administrative Tools group.
10. Choose the export Advanced Server, then choose Computer and Properties.
11. Choose Replication. In the Replication dialog box, choose Export
Directories. The Server Manager displays the default path:
C:\WINNT\SYSTEM32\REPL\EXPORT.
12. Choose Add. Specify the name of the domain or computer to act as the import
server. (Specifying the name of a domain replicates the files and
directories to any workstation or Windows NT Advanced Server in the domain
that is configured for import replication.)
NOTE: If you're setting up replication across a WAN, use specific computer
names instead of or in addition to the domain name. For additional
information, please see the following article in the Microsoft Knowledge
Base:

TITLE : Replication to Import Computers in a WAN Environment
13. Choose Manage to configure specific directories for replication. By default,
the Server Manager exports the Scripts directory that contains any user
logon scripts. Choose the Add button to specify any additional
subdirectories. (If necessary, create the directories first in the File
Manager or at the command prompt.)
If you choose the Add Lock button, Windows NT does not replicate the selected
directory until all <LOCKS> are removed. If you choose Wait until
Stabilized, Windows NT does not replicate files until two or more minutes
after the last file changed. Otherwise, Windows NT replicates files
immediately.
If you choose Entire Subtree, Windows NT exports the specified subdirectory
and all subdirectories it contains. Otherwise, Windows NT exports only the
specified subdirectory.
After you choose all applicable options, choose OK.
14. Choose OK to exit the Directory Replication dialog box. Windows NT responds
with the message "Attempting to Start the Directory Replication service on
<computername>." If the service does not start, refer to the Error Log
for specific error information.
Perform the following nine steps to configure the import server:
1. On each import computer, run Control Panel and select Services.
2. Choose the Directory Replicator service and choose Startup. Change the
Startup Type from Manual to Automatic.
3. In the Log On As control, choose This Account. Then choose Add User. Select
the replication account created on the export server and choose Add.
If the importing computer is in a different domain from the exporting
computer, set up a replication account in the import domain with the same
name and password as the account used for the export domain.
4. Type the password for the replication account and choose OK. Control Panel
responds with a message such as "The account DOMAIN\REPL has been granted the
Log On As A Service right and added to the Replicator local group." (If this
message does not appear, use the User Manager to grant this right. In User
Manager, choose Policies, then choose User Rights, and choose Show Advanced
User Rights. Check Log On As A Service and choose OK.)
5. Choose OK to dismiss this message.
6. In Control Panel, choose Server, then choose Replication.
7. In the Replication dialog box, choose Import directories. The Server Manager
displays the default path: C:\WINNT\SYSTEM32\REPL\IMPORT.
8. Choose Add. Specify the name of the domain or computer to act as the export
server. (By default, the From List is blank and the computer automatically
imports files from the local domain. If you add any entries to the From List,
the computer no longer automatically imports files from the local domain; if
desired, it must be added to the From List.)
If you're setting up replication in a WAN environment, use specific computer
names instead of or in addition to the domain name. For additional
information, please see the following article in the Microsoft Knowledge
Base:
ARTICLE-ID: Q139103
TITLE : Replication to Import Computers in a WAN Environment
9. Choose Manage to display the status screen for the imported directories. Add
Lock prevents Windows NT from updating the specified directory.
10. The Status field can be one of the following:
- - "OK" indicates that the subdirectory receives regular updates.
- - "No Master" indicates that the subdirectory is not receiving regular
updates.
- - "No Sync" indicates that the subdirectory has received updates, but that
its data is not up to date.
- - A blank status indicates that the subdirectory has not been replicated.
Additional notes:
- An Advanced Server can be configured as both an import and an export server.
- Windows NT can replicate files across domain trust relationships by
establishing the same Replication account and password in each domain.
- When Windows NT replicates files from NTFS to FAT, it replicates only 8.3
filenames.
- Windows NT can support other import and export paths. However, the default
paths, C:\WINNT\SYSTEM32\REPL\IMPORT and C:\WINNT\SYSTEM32\REPL\EXPORT, have
complex permissions that support replication. Maintaining these paths is
recommended.
- When Windows NT displays the message such as "The account DOMAIN\REPL has
been granted the Log On As A Service right and added to the Replicator local
group.", it indicates that the specified account has been added to the Backup
Operators and Domain Users groups by default in addition to the Replicator
group.
