NEW Error in SMS_MP_Control_manager - MP has rejected a message from GUID

MP has rejected a message from GUID:AA because the signature could not be validated. If this is a valid client, it will attempt to re-register automatically so its signature can be correctly validated.

From below query i managed to get the client name , i renamed SMSCFG file then it is working. Is there any way to automate this troubleshooting because 20 -30 machines are showing this error.

SELECT
Name0,
SMS_Unique_Identifier0
FROM
v_R_System
WHERE
SMS_Unique_Identifier0 = ‘GUID:AA'
