Some months ago one database here began getting an error message when users tried to open it saying "Error accessing file. Network connection may have been lost." The network connection was fine, however. Users were completely unable to use the database, though it can be opened with the bypass key. This has now affected two more databases but the exact cause is still unknown. This ONLY happens after the admins sync objects to the production databases from their test copies. Whether they use the import utility built into Access to sync objects or use the good ole drag-and-drop method, the result is the same. It obviously has something to do with bringing in new objects, but we are clueless as to the exact problem and how to fix or avoid it. The fact that the databases can be opened just fine with the bypass key or if the database window is set to open automatically when launched (instead of any forms), leaves me all the more baffled because the two issues should be entirely unrelated. As it stands, we're having to do a lot of extra work to get around this issue. Any help is greatly appreciated!
