actually , there are 5 logins including 'sa' login. none of them have the privilege to create database or change privilege except 'sa' login.
but 'sa' login is disabled.
when i tried to enable it using other user , it will fail( reason current login doesn't have privilege to change/add privilege).
i think there is login with syssdmin privilege ,only can assign privilege to other login....
i was trapped in all means.
i dont know how......?
