Hy I've done an upgrade of netbackup server from 3.4.1 to 4.5mp6 in 
Solaris8 (one master/media server with Solaris and some Solaris/windows 
clients) The upgrade was fine The Unix boxes make restores and backup 
without problems, all the policies are there with the correct settings 
etc..
But when I try to launch a manual backup on a windows client (3.4.1g)  
It doesn't even appear in the activity  windows and the  logs show that 
the scheduler fails with an error 12, looking at the troubleshooter it 
seems that I need a ¿new? file called 3pc.conf that isn't need at all 
for the Unix boxes and wasn't used in previous versions, this file seems 
very "strange" (scsi-id hd identifiers..) ¿is this file really need, 
I've see this on the upgrade procedures? ¿is there any way to create it 
automatically (/usr/openv/netbackup/bin/bptpcinfo -a)? ¿Maybe I've to 
upgrade windows clients?
