Tim,
        quite simply, I don't trust Protel nor the Access/Jet database and
my method can be quickly altered or changed by any of our MIS support
people. It is a shared resource, if I am run over by a bus tomorrow morning,
our MIS people can give access to edit the library file in approx. 10
seconds flat.
        After receiving advice or reading comments of others we do not touch
the database members/permissions, it is a trap waiting to spring shut. Since
we are running NT, we do not need another security measure/level that can go
wrong and screw us.

Sincerely,

Hi Brad,
If I read your advice right, you are setting the attributes of the database
for read only? Doesn't your approach defeat the purpose of the Protel
members/permissions? Why do you do it this way?

Lou,
We had a similar problem. The problem was caused by the 'saving' machine
being at SP6 whilst the others were not. Once all the machines were at SP6
the problem went away.

Cheers

TC

Luo,
        further to what Matthew has stated, I do exactly what I believe you
are doing. We are running NT4 and I load the reference library onto a
network drive, set the file 'attributes' to read only though the 'OS' and
everything is fine. We also get a message when loading the library, but it
is only a warning that the file is read-only and do we want to continue.

Sincerely,

Hi Luo:

Did you set it to "Read-only" using the database permissions, or the file
system permissions?

Use the database permissions, and see how you go there, if that's not what
you did.

Cheers,
MvdW

Dear All, 
As I had specified in the previous mail, I had put the library on the server
and shared them with others. For security, I set the library "read only" for
others, and only I get the full authority to access and modify the
footprints. But when other designer try to add the library to their PCB edit
environment, Protel alerts "file is not recognized", when I open all
authorities to everyone, then they can use the library correctly, But I am
afraid that is not security. How can I accomplish my original purpose?
Waiting for your good idea! Thanks.
Best Regards, 
Luo.
