What Are the Causes of Microsoft SQL Server Error 924?

  • Missing Database Files: One of the most common causes of Error 924 is the absence of necessary database files, such as the primary data file (.mdf) or the transaction log file (.ldf). This can happen due to accidental deletion, file corruption, or improper database detach/attach operations.
  • File Path or Permissions Issues: Incorrect file paths or insufficient permissions on the database files can also trigger error 924. SQL Server must have appropriate access rights to the database files in order to load and operate the database successfully.
  • Suspect Database State: If the SQL Server database was marked as “Suspect” due to a previous error or corruption issue, attempting to open it may result in Error 924.
