  • User-464753427 posted

    In my workplace I have a ASP.NET application running iin IIS 6.0 on Windows Server 2003 with Net 2.0 + 3.0 + 3.5 + 4.0.

    Backend database is MS Access MDB. When user logins to Application following error (See Below) is displayed at most of the times. But not always.

    It works well sometimes.

    Can you help out?
