When 4D Network Components are installed on Windows NT, they are to be placed in the following directory (where C: is the NT boot drive):

C:\WINNT\Aci\Network\

However, if you are using the Windows NT Terminal Server, the Network Components must be placed at the user level. Therefore, they must be in the following directory:

C:\WINNT\Profiles\username\Aci\Network\

NOTE: The "username" will be different for each user. In my case, the username is Jonathan Baltazar.
