Azure Stack HCI, version 21H2 servicing stack update - 20348.1300

This update makes quality improvements to the servicing stack, which is the component that installs Windows updates. Servicing stack updates (SSU) ensure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft updates.

Known issues in this update

Symptom

Workaround

After installing this update, apps that use ODBC connections utilizing the Microsoft ODBC SQL Server Driver (sqlsrv32.dll) to access databases might fail to connect. You might receive an error within the app or you might receive an error from SQL Server, such as "The EMS System encountered a problem" with "Message: [Microsoft][ODBC SQL Server Driver] Protocol error in TDS Stream" or "Message: [Microsoft][ODBC SQL Server Driver]Unknown token received from SQL Server".

Note for developers Apps affected by this issue might fail to fetch data, for example when using the SQLFetch function. This issue might occur when calling SQLBindCol function before SQLFetch or calling SQLGetData function after SQLFetch and when a value of 0 (zero) is given for the ‘BufferLength’ argument for fixed datatypes larger then 4 bytes (such as SQL_C_FLOAT).

If you are unsure if you are using any affected apps, open any apps which use a database and then open Command Prompt (select Start then type command prompt and select it) and type the following command:  

tasklist /m sqlsrv32.dll

This issue is addressed in KB5022291.

If you want to remove the LCU

Running Windows Update Standalone Installer (wusa.exe) with the /uninstall switch on the combined package will not work because the combined package contains the SSU. You cannot remove the SSU from the system after installation.
