To anyone that has netbackup and SEP and configure the network threat
protection...
The result of the combination of network threat protection and netbackup is
error 24. 

http://www.symantec.com/docs/TECH103087
Symantec Endpoint Release Update 6 Maintenance Patch 3 (RU6 MP3)
Symantec NetBackup communications lost when Symantec Endpoint Protection is
installed
Fix ID: 2114674
Symptom: Network communications are lost when a client running Symantec
Endpoint Protection is connected to a Netbackup media server, and the server
is under high load (e.g. multiple jobs running).
Solution: The Teefer2 driver was optimized to avoid a FIFO queue bottleneck
when processing SMB2 packets.

And the patch  http://www.symantec.com/docs/TECH134914
