how can I take down portal servers that I created and is being hosted by others

@RastaSmurf_473 if you are in the portal category of the BF2042 main menu and go over to the "host" tab, there it should then display your hosted server if it's still up because other players are still on it.

And at the side where the informatios of the server are displayed, you should also see the option to "take down".

Then it will kick everyone out and take the server down.

BUT if someone actually re-hosted your server by himself with those settings you made, then you can't take his one down as it is his server if he hosted it.

In this case it's a different server, not yours!

@RastaSmurf_473 Yo.
Seeing as dice removed persistent servers until season 6 comes out, any servers people host will die and shut down once no one is in it.
So the server that someone is hosting will eventually die at some point.
If you think someone has the experience code to your server and is hosting it repeatedly, you can do the following:

Duplicate the server in question at your end.
This will create a duplicate of the server but it will be allocated a new experience code.
Then delete your original one, which will also be the one the rogue hoster is using.
This will kill the code of the first, original server 👍🏼
