Voila je joue a battlefield depuis un moment en ligne et j´ai presque jamais eu de probleme.

Tout marchait bien jusqua hier , je me connecte a un serveur et au moment de jouer ca me kick et ca me met un message d´erreur du serveur. CE MESSAGE EST : "Restriction : service communication failure : PnKBstrB.exe initialization failed."

Est ce ke kelkun c´est pourquoi ca me met ca ? merci d´avance.

Verifie si ton pare-feu ne bloque pas le fichier PnKBstrB.exe

vu ton message d´avertissement, c´est un problème de PunkBuster. j´ai jamais vu ce message. ça te le fait à chaque fois ou c´était juste un coup?

salut
j´ai eu le meme souci hier ton pare feu a bloquer une application

La soluce :

Have you tried completely uninstalling and then reinstalling PunkBuster? Be sure to follow these instructions EXACTLY. People in the past have skipped parts and have failed to fix their problem.

1. Make sure that you either disable your firewall (probably not a good idea) or allow PnkBstrA.exe and PnkBstrB.exe access to do things (McAfee has been known to automatically add these services to the block list).
2. Download pbsvc.exe, which is a utility to uninstall and reinstall PunkBuster.
3. Open pbsvc.exe and select Un-Install/Remove PunkBuster Service.
4. Open pbsvc.exe again and this time select Install/Re-Install PunkBuster Service.
5. After installing, it will test your services. Make sure you get a "Test completed successfully without error." message. If not, then copy and paste the results of the test here.
6. Now download PBSETUP, which is a utility to update PunkBuster to the latest version. For Windows: pbsetup.exe
7. Open pbsetup.exe. It will probably have to check for updates, allow it to do that.
8. Click the "Add a Game" button at the top.
9. Select your game (in this case Battlefield 2) and make sure that the directory is correct.
10. Click the "Check for Updates" button at the top.
