Thanks to some guys here I found a Microsoft article which explains the use of the commands dsadd, dsmod and other Active Directory commandline tools.
However, I am not able to use this command on a 2000 Advanced Server with Supporttools and Adminpak installed as the command is apparently not recognized.
I searched and someone here mentioned that you need to install the adminpak of Server 2003 but the installer refuses to install it since it is not an XP based operation system ...
Do I need to install the resource kit ? None of the Microsoft articles actually says where to get those tools
