>Could you post some example data and desired result?

Here is an example, where I added Sergey's logic in it:
SELECT Master.Numero
FROM (SELECT Master.Numero FROM Master 
WHERE EXISTS (SELECT 1 FROM ManyToManyTable
 INNER JOIN ChildTable ON ManyToManyTable.NoChildTable=ChildTable.Numero 
 WHERE Master.Numero=ManyToManyTable.NoMaster
 HAVING COUNT(*)=SUM(CASE WHEN ChildTable.Enabled=1 THEN 1 ELSE 0 END))
GROUP BY Master.Numero) Temp 
INNER JOIN Master ON Temp.Numero=Master.Numero
