Call of Duty 4 PunkBuster Losing Packets error 9005 Fix
go to control panel then Adminstrative Tools then Services and look for PnkBstrA and PnkBstrB
double click on it and click the log on tab and check Allow Service to interact with desktop then click ok
do this for both PnkBstrA and PnkBstrB
you might just see only PnkBstrA on the list when you first go to services
if you do start cod4 and alt tab back to desktop and refresh the list and you will see PnkBstrB
