just place these files into your cod2/main folder on your own pc
connect to your server and execute the following commands:
/rcon login YOUR RCONPASSWORD
/exec pb.cfg (without putting rcon in front)

now your server execute the pb.cfg , cvar.cfg and md5.cfg. 
when its done the server will restart the map.

u DONT need to restart your PB after this.
now check if it worked out with /rcon pb_sv_LogPort
now u should see the following line into your console:

^3PunkBuster Server: pb_sv_LogPort = 11003 (1 to 65535)

if u need to restart your server any time your server will still stream. the only cfg u need to execute after restarting the whole server or the PB is the md5.cfg

then just do:
/rcon login YOUR RCONPASSWORD
/exec md5.cfg (without putting rcon in front)
