Hello, I hope there is still someone here who can help me. I have installed a MW3 server that runs so far (home network with dyn.dns).
The following message appears in the server window: version 1.9.388110

he server only appears in the Internet list, it cannot be found in the Lan list.

Anyone have an idea? I also copied steam.dll again into the MW3 directory. I am finished with my Ideas....
Can every one help me?

not recommend using home network.

i would suggest look for some vps that you can install this game.

being a hosted a game is what recommend as it puts less burden on the PC resources especially network .

The most use this to install a MW3 Server:

Your problem looks like a problem with firewall, closed port or wrong forwarding/ IP.

Wie heißt dein Server?
😋🙈

Helloo everyone, can someone give me a solution(that realy work) for my problem for MODERD WARFARE 3 (PC MULTIPLAYER NON-STEAM):
- I dont see list of dedicated servers anymore, and cant play online mp. Only have 1 server in RANKED section.
I tried several time to reinstall, downloading patches, etc. but nothing happens.
Currently i have version of game 1.4.382 , and Teknomw3 2.8.0.4b

No one is playing Tekno mw3 in 2022. Play on Steam or move to Plutonium. 😅
