[ILUG] Locked M$ DB

[Sonic]

Hi there,

Does anyone know how to unlock a M$ access db file. My mate has managed 
to forget the password (or set it wrongly as he put it) for a database 
which contains all his other passwords. I don't really use access so all 
I can tell you is that when I try to open it I get a message saying I 
don't have permission to open it.
Any help would be very much appreciated.

Cheers,

Sonic.
