ODBC Connection error since a few day's

[softboy12]

Hi all

One of our customer which uses a Access driven Intranet Application receives the following error message:

Microsoft OLE DB Provider for ODBC Drivers error '80004005'

[Microsoft][ODBC Microsoft Access Driver] Cannot open database '(unknown)'. It may not be a database that your application recognizes, or the file may be corrupt.

i checked and fixed the database and reconnect the ODBC Connection but this dosen't solve my problem

after i restart the IIS the database connection works

what coud be the problem?

thanks in advance for your trouble

best regards
