Windows: November 2022 updates cause ODBC connection problems with SQL databases

Update[German]It looks like the Windows updates released by Microsoft in November 2022 may cause problems accessing SQL databases. Then the ODBC driver triggers a database access error. According to Microsoft, all Windows versions that are still supported (both clients and servers) are affected by this problem. There is no solution for this problem yet.


Microsoft has confirmed the problem as of Dec. 5, 2022, in the Windows Release Health status area (for example, of Windows 11 22H2) in the post Database connections using Microsoft ODBC SQL Server driver might fail. It states there:

After installing [the xxxx update], applications that use ODBC connections with the Microsoft ODBC SQL Server driver (sqlsrv32.dll) to access databases may not be able to connect.

You may receive an error message within the application or you may receive an error message from SQL Server, such as.

The EMS system has detected a problem
Message: [Microsoft][ODBC SQL Server Driver] Protocol error in TDS stream


Message: [Microsoft][ODBC SQL Server Driver]SQL Server Driver]Unknown token received from SQL Server

The following Windows client versions are affected if the appropriate November 2022 update is installed:

and also the following Windows Server versions

To check whether the driver for Microsoft SQL Server is affected, the following command can be entered in an administrative command prompt.

tasklist /m sqlsrv32.dll


If the process appears and the error is reported, the system is affected by the problem. So far, there is no fix (other than uninstalling the update). Microsoft is working on this problem and wants to fix it via update in the future. (via)

One Response to Windows: November 2022 updates cause ODBC connection problems with SQL databases

    Could the servicing stack update – 17763.3641 installed on the domain controller be potentially the cause of those errors connecting from a client to DB?
