Gussie presented the following explanation :
Have you tried any other providers? I have been using the Sql Native
Client driver for years in Access to connect to a variety of sql
servers. Something like:
Driver={SQL Native
Client};Server=myServerAddress;Database=myDataBase;Uid=myUsername;Pwd=myPassword;
I am currently using that specific provider to connect to a Sql Server
that is being hosted by Amazon Web Services. That connection is being
used both to link tables/queries, and VBA code things. Haven't had a
lick of a problem.
There is a VERY good web site resource for connection strings at
https://www.connectionstrings.com/ I think that if you spend a little
time there you will likely find something that works.
