Hi.
Locks up as in "The database has been opened exclusively or you do not
have
permission to open it. Please see your Adminstrator"
A number of things can cause this:
1.) The most likely cause is that the database is using Jet 4.0 with a
shared front end file, only one user has the file open and that single user
makes a change to a database object or creates a new database object, which
elevates the mode to "exclusive." Until that change or new object is saved,
the file will remain in exclusive mode (even if the user originally opened
it in shared mode), and no one else will be able to open it. The solution
to this problem is to distribute a copy of the front end to each user so
that no one is sharing that file when it needs to be elevated to exclusive
mode.
2.) One of the users is unknowingly opening the front end in exclusive
mode. Check each user's "Default open mode" setting. Each user must open
the Tools -> Options... menu to open the Options dialog window, then select
the Advanced tab and ensure that the "Shared" option under "Default open
mode" is selected. (But it's better to just distribute the front end to
each user.)
3.) User-level security has been applied and the user doesn't have "Open
Database" permission. (If you haven't applied user-level security, then you
can rule this out. If you've applied user-level security, you can rule this
out if this user can open the database at other times while joined to the
secure workgroup.)
4.) The database file is corrupt. (Make sure that back ups are made
_before_ the database bites the dust.)
HTH.
