Update query not updating

[John]

Hi

We have this strange problem on an access 97 app over a network. The backend
db is on a win2003 server and each pc has the front rend linking to the back
end. The app runs an update query which works fine on one pc. On another pc
the query fails and is unable to update the records? Why would this be that
one pc can update the records on the server but not the other? The user
seems to have all the rights as far as I can see.

Thanks

Regards

What error do you get? And what's the query doing?

The first thing I check when an application works on one machine but not on
another (or when it suddenly stops working on a machine where it previously
worked) is that there isn't a problem with the References collection.

References problems can be caused by differences in either the location or
file version of certain files between the machine where the application was
developed, and where it's being run (or the file missing completely from the
target machine). Such differences are common when new software is installed.

On the machine(s) where it's not working, open any code module (or open the
Debug Window, using Ctrl-G, provided you haven't selected the "keep debug
window on top" option). Select Tools | References from the menu bar. Examine
all of the selected references.

If any of the selected references have "MISSING:" in front of them, unselect
them, and back out of the dialog. If you really need the reference(s) you
just unselected (you can tell by doing a Compile All Modules), go back in
and reselect them.

If none have "MISSING:", select an additional reference at random, back out
of the dialog, then go back in and unselect the reference you just added. If
that doesn't solve the problem, try to unselect as many of the selected
references as you can (Access may not let you unselect them all), back out
of the dialog, then go back in and reselect the references you just
unselected. (NOTE: write down what the references are before you delete
them, because they'll be in a different order when you go back in)

The References problem, as Douglas suggests, would be the first place
to look. The next would be to check that the user of the failing PC
has COMPLETE read, write, create, and delete permissions on the folder
containing the backend: this is necessary in order for them to create
and delete the .ldb permission-locks file associated with the
database.
