PB INIT Failure

[goody10]

There have been reports of clients getting kicked with the error message "PB INIT Failure"
This is not restricted to Cod but has effected other pb games as well.
To fix it just manually update PunkBuster. You can do that by going HERE
And getting the setup software for you O/S

PunkBuster kicks me for INIT FAILURE, what does that mean?
Usually, this message means your PB is not working properly. You should run our PBSETUP program to make sure your PB is up to date.
However, we have recently discovered that some broadband routers routinely drop OOB (Out of Band) packets for no apparent reason. Since all PB packets are OOB, these routers can actually block PB's communication (again for no apparent reason). To determine if the router is the cause of this problem for you, remove the router and connect directly to the internet. If you are able to play this way, then the cause is very likely the router.
Based on user feedback, the following router brands/models are reported to have problems. Not necessarily all models of a brand might be affected, and the list is in no way complete but it can give you a few hints. Also, we do not claim that our list below shows the only solution to fix your issue, nor that it will fix it for sure even though it has worked for others. It could very well be that changing some settings in your router could help as well. Contacting the company directly might help you as well.

Linksys - possible solution: Use firmware
1.44.2Motorola - possible solution: Update to latest firmware
Netgear - possible solution: Disable SPI (statefull packet inspection)

This is the official answer from PB I got this one in an email hope it helps

Note #2: The kick in CoD4 was caused by your client not being able to update to the latest PB. The quick fix is to join a server and drop down the console with ~ ( the button to the left of 1 ) and type \pb_security 0 and hit enter. This will allow your client to update.

The reason this appears to have happened is do to your system not being able to get the latest security information from our masters. This could be due to a firewall blocking communication on UDP port 28962. Please open that port on any firewall you may have active. PB needs that port to get security information and update PB properly.
