We recently installed a SQL Server 2016 Standard instance on a Windows Server 2012R2. When we are trying to create an OLEDB connection we receive the following error

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

enter image description here

I searched the internet and non of the solutions worked for us. https://support.microsoft.com/en-ca/help/3135244/tls-1.2-support-for-microsoft-sql-server

Microsoft has released new OleDb driver which supports TLS 1.2. https://blogs.msdn.microsoft.com/sqlnativeclient/2018/03/30/released-microsoft-ole-db-driver-for-sql-server/

TLS1.2 does not support OLEDB connections
