This is perfectly normal, battleye is blocking one of the dll's packaged with NVIDIA's driver packages, I don't think that there is any harm with BE blocking the one you've listed though as its for 3D Vision and not related to NVIDIA Shadowplay/Share.
try running steam as admin. if it is a vanilla server, make sure to use the steam-dayzmod browser.
Personally I'd advise against using the workshop copy as I've had issues with it, running steam as admin may resolve it but it shouldn't be used as a long term fix, it could be a issue with additional launch parameters in the settings tab.
When i play arma 2 dayz epoch,i can't see zombies or some vehicles which my friends can when they are in the same game/server as me?
This would likely suggest that the server isn't correctly setup to kick you if the mods needed aren't loaded, or you have a out of date mod you should probably contact the server owner about this issue first.
