Windows Server 2022 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 through Microsoft ODBC SQL Server Driver (sqlsrv32.dll) to access databases might not connect. Additionally, you might receive an error in the app, or you might receive an error from the SQL Server. Errors you might receive include the following messages: The EMS System encountered a problem. Message: [Microsoft][ODBC SQL Server Driver] Protocol error in TDS Stream. The EMS System encountered a problem. Message: [Microsoft][ODBC SQL Server Driver] Unknown token received from SQL Server. To decide whether you are using an affected app, open the app that connects to a database. Open a Command Prompt window, type the following command and then press Enter: tasklist /m sqlsrv32.dll If the command lists a task, then the app might be affected.	We are working on a resolution and will provide an update in an upcoming release.
After installing this update on Hyper-V hosts managed by SDN configured System Center Virtual Machine Manager (VMM), you might receive an error on workflows involving creating a new Network Adapter (also called a Network Interface Card or NIC) joined to a VM network or a new Virtual Machine (VM) with a Network Adapter joined to a VM network. Existing VMs with existing Network Adapters should not have issues connecting after installing this update, only new Network Adapters created after installation of this update are affected. When experiencing this issue, you might receive one of the following errors: When creating a new VM or a new network adapter on an existing VM, you might receive, "<vmName> failed to modify device 'Ethernet Connection" Software defined networking (SDN) software load balancer service might fail, and you might receive, "<SLBVMName> failed to modify device 'Ethernet Connection' error" SDN RAS Gateway service might fail, and you might receive, "<GatewayVMName> failed to modify device 'Ethernet Connection' error"	To mitigate this issue, open an elevated PowerShell window (select the Start button then type powershell, right click or long press on it and select Run as Administrator) on all SCVMM managed Hyper-V hosts and run the following commands: $lang = (Get-WinSystemLocale).Name C:\Windows\system32\wbem\mofcomp.exe C:\Windows\system32\wbem\en-US\VfpExt.mfl C:\Windows\system32\wbem\mofcomp.exe C:\Windows\system32\wbem\VfpExt.mof A script with this workaround for large scale deployments and a post-install script that can be integrated with patching tools are available in Win12B issue in System Center Virtual Machine Manager. We are working on a resolution and will provide an update in an upcoming release.
