1. Navigate to the share in Windows Explorer.
2. Right-click on the share, select Properties to display the Properties dialog box.
3. From the Sharing tab, review the permissions.
4. Allow access only to approved users.
5. Click OK.

To remove the share:

1. Open a command line.
2. From the Windows NT Start menu, select Run.
3. Type cmd, then click OK to open the command line.
4. Type: net share sharename /delete, where sharename is the name of the share.
5. Type exit to return to the Windows NT desktop.

From a remote host, remove the share:

1. Open User Manager. From the Windows NT Start menu, select Programs, Administrative Tools (Common), User Manager.
2. Select the host. From the Computer menu, select Shared Directories to display the Shared Directories dialog box.
3. Select the share and click Stop Sharing.
