If you have ever faced the problem of a lost database due to an erroneous ACL and "Enforce a consistent ACL across all replicas" was set...

You may still recover this database by running this script locally on the affected machine.

Actually, althought direct access and LotusScript access are denied, programs written with Notes API, can access and change this flag.

Below is the code (hope will help... it should!).

You can create an EXE file to convert this into a tool (I did but I can't submit it here)...
