ADO or Active Database Objects can be referred as the technology which permits the Active Server Pages (the processing technique at a web server) to access databases. These tools allow the client applications to process the data in the database server through any OLE DB provider.
But this whole process can become problematic in few instances when using them to connect to the Access database and fails to do so with the following error message:
Microsoft OLE DB Provider for ODBC Drivers error ‘80004005′
[Microsoft][ODBC Microsoft Access 97 Driver] The Microsoft Jet database engine cannot open the file ‘(unknown)’. It is already opened exclusively by another user, or you need permission to view its data.
This instance forces the users to think about the contributing causes due to the inaccessibility of the database.
Reason
There may be several reasons for the problem. This may happen that the database is opened at some end when connection is being attempted to make or the IIS account does not retain the necessary permissions to access the folder that contains the file. This error message may also account for the delegation issues. So use the basic authentication or an absolute path.
If the local database, which is linked to a table placed on the network server, is attempted to access, then you may encounter this error message. In the most weird instance, the database may be corrupted which is halting the process of connection as this may happen when you use the MS Jet with IIS application.
Solution
As per the case may be, the corrective measures run accordingly. At the first, you need to check the permissions on the file and folder. You also need to check that the file and the data source name are not marked as exclusive.
But if the database is corrupt, then its better to check for the access repair tools which can make a perfect scan of the corrupted database and hence repair and restore the corrupted data.
Access recovery software are the utilities which can end this job perfectly. They come equipped with the interactive user interface and hence offer the ease of use to the users. You can have them for different versions of MS Access for the best Access repair results.
