  I also seem to get the cookie warnings a lot 

Resolution: Under my deployment package i selected all the updates and right clicked and selected Refresh contents. This re-downloaded all the updates and then I updated my distribution points.

I have experienced this issue a couple of times at my organization and every time this solution has worked.
if above step doesn't work try un-insattling> re-installing  sccm client. Rebooting machine once
