Microsoft Ole Db Provider For Sql Server Tls 1.2 !!hot!! -

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Client] "Enabled"=dword:00000000

Use Wireshark or netsh trace to observe TLS handshake:

Therefore, if your application uses Provider=SQLOLEDB and the SQL Server or Azure SQL Database requires TLS 1.2, the connection will fail with errors such as: microsoft ole db provider for sql server tls 1.2

netsh trace start capture=yes provider=Microsoft-Windows-Schannel tracefile=c:\temp\tls.etl

To ensure compliance and stability with TLS 1.2: Failure to do so results in connection failures,

The only Microsoft-supported OLE DB provider that fully supports TLS 1.2 (and TLS 1.3 where applicable) is (Microsoft OLE DB Driver for SQL Server).

: The latest version can be found on the Microsoft OLE DB Driver for SQL Server page. security audit findings

As part of industry-wide security initiatives (PCI DSS, NIST, HIPAA) and Microsoft’s deprecation of older TLS protocols (TLS 1.0 and 1.1), it is mandatory to ensure that all Microsoft OLE DB Provider for SQL Server connections use . Failure to do so results in connection failures, security audit findings, and exposure to protocol-level vulnerabilities (e.g., POODLE, BEAST). This document details the requirements, provider limitations, and step-by-step remediation for systems using the legacy SQLOLEDB provider and its modern replacement, MSOLEDBSQL .

While generally discouraged, some limited TLS 1.2 support was added to the legacy sqloledb.dll through Windows OS patches:

: You must have Windows 10 Build 17763.1554 or later (Windows Server 2019 equivalent) for these MDAC components to recognize TLS 1.2.
