In addition to Ram's excellent post:
Logs to check: PBX log and server.log.
PBX log is not plain text. You need vxlogview to view the log.
After you have restarted PBX, we need to see if it stays running.
Open cmd to run vxlogview:
(cd <install_path>\NetBackup\bin)
vxlogview -p 50936 -i 103 -t 00:05:00
(above command will display log entries for last 5 minutes)
You can send output to a .txt file and upload here (assuming you have C:\Temp folder):
vxlogview -p 50936 -i 103 -t 00:05:00 > C:\Temp\pbx-log.txt
server.log is plain text and located in <install_path>\VERITAS\NetBackupDB\log\
Copy the file to server-log.txt and upload here using the 'Choose Files' link.
