How can I enable or modify user accounts in the GoAnywhere database when the service is shut down?

With the service stopped, you can use Apache Derby or DBSchema to open the database folder and run SQL commands directly. For example, to enable the root user, execute `UPDATE APP.DPA_USER SET ENABLED='1' WHERE USER_NAME='root';` and to set a password, update the `USER_PASS` field with a precomputed hash. This method is useful during vulnerability research, as shown in the GoAnywhere Managed File Transfer Vulnerability Debugging Environment Setup article.
