@CYFN Thanks for that.

I did a lot more testing and I found if I turned off IPS on the new security device it fixed the issue. Not only with Morphos but also other computers trying to play large movie files.

Strange that IPS would do this? So I don't think it is the QNAP but the new security appliance. Strange because is has a lot of cpu grunt and power and is a new next gen device...
