When an application reports that it cannot connect to its database, verify the connection in a controlled order.
- Confirm the database still exists in Manage My Databases.
- Confirm the configured database username is correct.
- Confirm that user is assigned to the database with the required privileges.
- Verify the password stored in the application's configuration.
- Verify the database host value.
- Use the database check tool if corruption is suspected.
Do not reset multiple passwords and rename databases at the same time. Changing one variable at a time makes the root cause easier to identify.
