Network Security

[David]

If anybody could help with the following problem, I would
be most grateful,

I have a database that was used on one computer by three
groups of people Adims, Full data users, and read only
users. I set these groups and users using the ‘user level
security’ wizard
I set passwords for each individual, and everything worked
fine. Now I wish to share the database across a network.
So I moved all the files to a shared folder on the
network, the problem is when I open the database from my
computer I have to fill in my user name and password but
if I use a different computer on the network the database
opens and nothing is secure.

Thanks

Dave
