If another user has opened the file in single-user mode, no other user can access it until it's closed or switched.

A damaged company file or log file (.TLG) can also result in this error.

Multiple systems may have hosting turned ON, which causes conflict in multi-user setup.

Corrupted or misconfigured .ND (Network Data) files can cause this error while accessing the file over the network.
