There was another issue that came up with the 1903 update. Copying files directly to a share stopped working and the solution was to create a sub-folder and point to that location. The solution I posted there is:
"My shared before pointed directly to a share on my server, the target was "\DC\share" in the property section of the shortcut I change the target to "\DC\c$\share".
It seems as though if the share is not pointing directly to the share then all works okay.
Hope this helps"

This seems like the same solution may be helpful with Access corruption after seeing what worked for George.
The solution that worked for us is the LifetimeCache modification on all FE machines. We have not had any corruption errors in several months after implementing that fix.
