Database Error (Operation = GET-LE, Error = 0) [Microsoft][SQL Server Native Client 11.0] Communication link Failure ....

The error above appeared on one workstation only at a client when posting a Purchase Order.  This workstation was fine for several months after the upgrade

They were recently upgraded to Sage 300 v2021 PU2.  They are also integrated with CRM 2021 if that matters.

This looks like some kind of ODBC setup error but not sure.

Has anyone seen this before?
