Microsoft is working to address a new known issue affecting applications that use ODBC database connections after installing Windows November 2022 Patch Tuesday updates.

According to Redmond, affected applications may not connect to databases through connections using the Microsoft ODBC SQL Server driver.

“After installing this update, applications that use ODBC connections through Microsoft ODBC SQL Server Driver (sqlsrv32.dll) to access databases may fail to connect,” Microsoft Explain.

“Also, you may receive an error in the application or you may receive an error from the SQL server.”

The list of potential errors that users may see on affected systems include:

• The EMS system has encountered a problem. Message: [Microsoft][ODBC SQL Server Driver] Protocol error in TDS Stream.

• The EMS system has encountered a problem. Message: [Microsoft][ODBC SQL Server Driver] Unknown token received from SQL Server.

The known issue affects both Windows client and server platforms, from Windows 7 SP1 and Windows Server 2008 SP2 up to the latest versions of Windows 11 and Windows Server 2022.

How to check if your apps are affected

Windows users can use the following steps to check if any of their applications are using ODBC connections to connect to a database and might be affected by this known issue:

1. Open any applications that use a database, then open the command prompt (select Start, then type command prompt and select it)

2. On the command prompt, type the following command:

   tasklist /m sqlsrv32.dll
   

Microsoft added that it is currently working on a resolution, with more details regarding this issue to be released with a future update.

The company is investigating domain controller hangs and restarts since November 25, also triggered by Windows Server Patch Tuesday updates from last month.

A week earlier, Microsoft addressed domain controller login failures and other authentication issues caused by November Patch Tuesday Windows Updates with Emergency Out of Band (OOB) updates.
