Right, same mess. I don't have time to spare. As Divad_S wrote: "Like all thinks MOCOsoft (microsoft), when in doubt reboot.  I am sure glad they don't make AIRCRAFT."

Forget me.

We discovered a subtle difference for this problem.

The back-end database was fine. We could open it from another machine without a problem. From the machine with the problem, we found we couldn't open any database on the network.

Turns out it was a problem with the workgroup security file (MDW) that it was referencing. It had gotten corrupt. Access was being launched with a shortcut that included a /wrkgrp command line parameter that pointed to that MDW file.

Once we pointed it to another MDW file, it worked fine.

In our case it was relying on group policy preferences GPP map drive configuration.

The drive from which the database was started was mapped with GPP option "replace".

This caused msaccess to loose connection when standard group policy event raised.

Solution was setting option to "update".
