Windows NT’s easy-to-use file server functionality allows
users to access files over a network through a share folder that holds the
files. You can create this folder by right-clicking any folder and selecting
the Sharing option. Then, all you have to do is select the name for the share
and define the permissions.

Windows NT 4 stores all share information in the registry.
This allows you to export the information from one machine and import it into
another. To access the share information, open the Registry Editor by going to Start | Run, typing regedt32.exe, and clicking OK. Then,
navigate to the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\
LanmanServer\Shares

This registry key lists all shares. To move a share from one
server to another, follow these steps:

  1. In the
    Registry Editor, go to Registry | Export Registry File.
  2. Save
    the settings in a .reg file by selecting a location and clicking Save.
  3. Close
    the Registry Editor.
  4. Copy
    the .reg file to the destination computer.
  5. Right-click
    the file, and select Merge.

In order for the shares to show up, you’ll need to restart
the machine. Or you can start and stop the server service (enter Net Stop
Server and then Net Start Server at the command prompt) and other
services that require server service.

Be aware that this procedure will migrate all of the shares
from the source machine. In addition, you must store the folders on the same
drive as before. For example, if you copied the C:\test share from one machine,
you must copy the folder to the same location (C:\test) on the destination
machine.

Note: Editing the
registry is risky, so be sure you have a verified backup before making any
changes.
