    HI.

    Destination DB version SQL 2016, So application does not able to connect database. connection string using Provider=sqloledb;

    Error:

    ConStatus Error [DBNETLIB][ConnectionOpen (SECDoClientHandshake()).]SSL Security error.

    Destination DB server windows 2019 version and TLS 1.0 client by default disabled, So I made it enabled as below location in registry setting but not hope and not resolving issues.

    'HKLM:SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Client' -Name 'Enabled' -value '00000001'

    In Application server does not connected to database server due to SQLOLDB driver, how to resolve this error?

    Please suggest.

    Thanks

    Are you sure it's the driver causing the issue, rather than the deprecated TLS protocol? You should probably be aiming to use TLS 1.2.

    SQLOLEDB does not support TLS1.2.

    so you need to ensure there is a common protocol on both client and server which can be used is you must use that driver (TLS1.0).

     

    Secondly that driver has been deprecated for decades now (went into depreciation in SQL 2005)

    Upgrade the driver to msoledbsql for TLS1.2 support.
