Hi Batista,

1. Check the mode in which you are opening the database.
2. Check for the network rights.
3. Check database for corruption . Try repair.
4. Check for any other user using the same database in any application or by any means.
5. Try making a dns and check for connection.
6. Check for driver corruption.
