I have Solaris 8 Netbackup 5.0 MP4. Backups are working fine for all clients EXCEPT- When I configured new policy for new Windows 2003 server the backup is not working. This is what is happening. Activity monitor -I can see the job then connecting-mounting-begin writing. Then the message in Activity monitor's job overview- (42) Network read failed. In Detail view the messages are- error bptm (pid 2462) - system call failed. Connection reset by peer (at child.c.1177) error bptm (pid 2462) unable to perform read from client socket connectin may have been broken. After sometime kill the job. I went to host properties for Master- select Timeout and tweak/play with all the parameter with 0 to 32767 range settings without any change in error messge- no success. Now sometime it works eventhough I see the message. I do not have some third party software that conflict with this. Network duplex settings are fine too. I check this forum and these were two sujjestion I found. PLEASE Help! Thanks in Advance.
