96C73A1F Integrity check fails.
Explanation
The checksum computed using the decrypted message is not the same as the checksum contained within the message. This error can occur if the message has been modified or the wrong key was used to decrypt the message. The key can be incorrect if a password change has occurred for the principal. This error can also occur if the checksum contained in the authenticator does not match the checksum computed using the supplied application data.
User response
Verify that the message was not modified. If an incorrect key was used, retry the request with the correct key. Contact your service representative if the error persists.
