If you met a problem when you joined to a server which has a PunkBuster and you have been kicked due to
RESTRICTION: Service Communication Failure: PnkBstrB.exe initialization failed
Then the solution is the following:
- Download the PunkBuster, pb folder from here.
- Go to the CoD folder and rename the current pb folder to e.g. pb1
- Extract the whole pb folder what you downloaded and copy paste into the Call of Duty folder to the same place where the previous one was
- Run the pbsvc.exe, a black window is going to pop up and wait until you get the message that you are done and you can close the window
- Go back to the server and enjoy the game, have fun 🙂 If you still have an issue please send us a message either here or on Facebook.
