Are there updates to SQLSRV32.DLL driver to support TLS 1.2? Version 10.00.18362 seems to broker a successful #TLS 1.2 handshake to #SQLServer 2016

SQLSRV32.DLL is the old SQL Server ODBC driver that's part of Windows.

In October 2020, Windows finally dusted off the source code for the built-in ODBC and OleDb SQL Server drivers and updated them to support TLS 1.2. See KB4580390.

  • Thank you David. Is is accurate to say that the SQLSRV32.DLL is no longer deprecated? Commented Dec 9, 2021 at 10:45
  • The changes announced in KB4580390 don't comment on data access protocol (sys.dm_exec_connections.protocol_version) and interface TDS protocol (sys.dm_exec_sessions.client_version). Using SQLSRV32.DLL to connect from a client, SQL Server 2016 reports these two values as "SQL Server 2000 SP1". Given KB4580390, are the reported values correct? Commented Dec 9, 2021 at 11:00
  • It was never technically deprecated. Just old. And it’s still a client from the SQL 2000 era. But it’s supported but not being actively enhanced. The new ODBC driver is still recommended. learn.microsoft.com/en-us/sql/connect/odbc/… Commented Dec 9, 2021 at 11:53
