We figured out what the problem was. After upgrade, selecting multiple docs to sign-off was turned off. We had to turn it back on. That took care it.
As far as scanning documents - all scanned documents go into a folder on the server that is shared. We created a share for the specific purpose. This share sits on all front-office desktops. Front office folks then move it into AC. All this is relatively straight forward - setting up preferences as to where the scanned docs are stored, creating shares etc.,
As Bert suggests as a general rule except sys admin, no one should be physically on the server.
Hope this helps.
