The thing is I receive from the server a list of codes and to deliver it to the user I search the names in the mdb. From the time te user places the request and before I get to deliver the entire route I get the 'couldn't lock' file message. Even If I press Ok the route delivered is not complete so I can probably get into the mdb file to get some of the names but for some reason it stops.
It's a local mdb file placed on the user's C: directory.
If I request the same route from another computer it works out fine: same mdb (copy-pasted it)
Most of my users don't get this error. It has appered so far on 3 of them.
I checked the rights, I can move-it, delete it etc...
