Hello Phillip J. Seaman, thank you for reaching out to the Q&A forum and I apologize for the delayed response.
First, I recommend reviewing the AI-generated response on your post as it offers some helpful insights that align closely with my own thoughts on the issue.
Additionally, I’d like to point out that recent updates to Microsoft Access have introduced tighter security around SQL queries that reference external databases. This change may be contributing to the behavior you’re seeing. I recommend reviewing the following article to determine whether it applies to your scenario: Query Reference to Remote Database Fails.
