    Hi all,

    My control Panel suddenly showing this error:

    ERROR: PleskMainDBException
    <b>Source:</b> Microsoft OLE DB Provider for SQL Server<br/><b>Description:</b> [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.

    0: common_func.php3:600
    db_mssql_connection()
    1: common_func.php3:629
    reconnect()
    2: common_func.php3:590
    db_connect()
    3: auth.php3:87

    After do some digging, in Event Viewer it show SQL evaluation period had expired. Already reinstall the MSSQL,
    but same error still occurs. Any idea how to fix this issue? Thanks

    Are you sure that MSSQL password for 'sa' user is the same that in Plesk psa database?
