Macola7.ini is a local file, if there is such an option, you would have to do this to every single workstation.
In Progression, you do this to the macola7.cfg file (in the macola root directory) and the line is Lock-Out=YES.
I do not believe this works in ES.
Here is some SQL that should help:
1) Revoke permissions for everyone except yourself
begin transaction
update humres
set backofficeblocked=1
where res_id<>your id
2)Then when you are done with month end, restore the permissions
rollback transaction
Having said all that, why do you feel a need to lock everyone out while you are doing month end?
