The cause of this conflict is currently being investigated. At this time, it appears that the code injection that Application and Device Control performs may cause a conflict with Netbackup DLO agent in certain hardware/driver configurations.
A permanent fix is being investigated by Symantec engineering.
In the meantime, the following workaround has proven to be successful in some Symantec and customer configurations to mitigate the issue.
A centralized exception must be added to your SEP Client policy using the Symantec Endpoint Protection Manager (SEPM) console. The exception cannot be made on the client directly, as the client lacks the capacity to make ADC exceptions.
In the SEPM console, access the Policies panel. Click on Exceptions and then edit the exception policy you currently have in place for your test group.
In the exceptions heading of the policy window that opens up, click the Add button, then choose Windows Exceptions and File.
Check the box next to Application Control, and then use the full file path for the DLO client. The path can be: C:\Program Files (x86)\Symantec\NetBackup DLO\DLO\DLOClientu.exe (adjust as necessary)
Click OK, and then OK again to exit the policy window. This policy should now be applied, and your clients will receive it as soon as they check in with the manager. You can force a manual policy update by right clicking on the shield icon on one of your clients, and choosing "Update Policy".
Policy changes typically go into affect immediately, but if you may need to reboot in the event the exception does not appear to work.
If you are experiencing trouble with this workaround, or are experiencing this issue and have not yet created a case with Symantec Support, please call our support line and open a case so we may assist you and adequately track the scope of this issue.
