Failed to Decrypt Protected XML Node "DTS:Password"

Understanding the Error

The error 'Failed to decrypt protected XML node DTS:Password with error 0x8009000B' is commonly encountered when executing SQL Server jobs that include SQL Server Integration Services (SSIS) packages. This issue arises when the SSIS package attempts to access encrypted sensitive information, like passwords, that cannot be decrypted due to missing or incorrect security keys or settings.

Common Causes

This error can occur due to several factors, including but not limited to the following issues. Understanding these causes can help in troubleshooting effectively.

Potential Triggers for the Error

• The SQL Server Agent account lacks permissions.
• Missing or incorrect Service Master Key.
• Package stored in a SQL Server database and not in file system.
• Environment mismatches between development and production.

Solutions to Decrypt Protected XML Nodes

To fix the error and successfully decrypt the protected XML node, consider implementing the following strategies. These solutions aim to ensure that the necessary keys and permissions are properly configured.

Effective Solutions

• Ensure that the SQL Server Agent is running under an account with the appropriate permissions.
• Use the SQL Server Management Studio to recreate the Service Master Key.
• Deploy the SSIS package as a project deployment instead of a package deployment.
• Consider using parameters to pass sensitive information instead of hardcoding passwords.

How to Recreate the Service Master Key

Recreating the Service Master Key on your SQL Server instance can often resolve decryption issues. This process will help recover access to encrypted components, including SSIS packages.

Script to Recreate the Service Master Key

USE master;

GO
-- Recreate the Service Master Key
ALTER MASTER KEY REGENERATE WITH ENCRYPTION BY PASSWORD = 'YourSecurePassword';
GO
