Network shared files on another mac require verification before viewing

[seanbperiod]

I have 2 computers, both on High Sierra. Previously, I was able to double click a file on a network share and it would open immediately. But with High Sierra, most files now have to be "verified" before viewing. This is especially problematic when they are large sized video files- and they seemingly have to be verified/downloaded onto the local computer before viewing, instead of streaming.

I'm also unable to delete folders over the network share. It will appear like it's deleted, but after a few seconds, the folder will reappear.

Both computers have FileVault and GateKeeper disabled.

Any others experiencing this? Any fixes?
