"Network connection was interrupted" error with shared Access database
Has anyone else encountered the same issue?


Yes. The Access Database Engine is designed to work with "real" Windows file sharing and Samba &ndash; or at least some versions of Samba &ndash; apparently do not implement all of the low-level features of the SMB protocol that are needed for the Access Database Engine to work reliably.
