If you mean a plugin dll, they go in the plugin folder in your server directory.

Create "plugins" folder in your server directory. If you are using Windows, place .dll file, if you are using Linux, place .so file. Then go to server.cfg and add new line to it, "plugins PluginName.dll". That should do it.
