Camera Raw not opening DNG acoss network drives

On a Mac (tested this on three Macs and two PC's). I work in an environment where we store all our studio images created on Macs on network PC servers. Recently we were not able to open any of the DNG's from Camera Raw 11.2 on the Macs without changing any settings on previously finished DNG's. But if you changed any setting by the smallest or largest margin, the file would open in Photoshop only if you viewed the file through Camera Raw in Bridge. No matter what you did, the file would not open in Photoshop if you just double clicked the file in Bridge or the finder. Command + R opening in Bridge would allow you to change a Camera Raw setting and then you could open the file (change anything means: color temp, tint, exposure, contrast etc all the down the line). You only needed to change one box and the file would open in Photoshop. Go back to Bridge Camera Raw and return the changed setting to its previous value and it again would not open. It acts like its sending it to Photoshop meaning Photoshop would activate, but nothing would open.

This was not a problem on the two PC's we tried it on. This was not a problem on local drives or local network drives such as a NAS or Drobo connect to the Mac it self. Only if over a regular network. We tried three different servers and had the same results for both Mac and PC. Mac's Camera Raw broken and PC's working. We restarted the computers, reset Photoshop prefs and purged caches for files and folders.

After all that testing, we reverted the Mac's to Camera Raw 11.1 and that fixed the problem. Reinstalled Camera Raw 11.2 and problem returned.
