Windows 11 25H2 SQL Server Native Compiled Stored Procedure Parameters Out of Range Issue

Symptoms

• SQL Server native compiled stored procedures fail with parameter validation errors
• Error messages indicating 'parameters out of range' when executing native compiled SPs
• SQL Server Management Studio (SSMS) shows parameter mismatch warnings for native SPs
• Event Viewer logs containing SQL Server CLR runtime errors related to parameter marshalling

Likely causes

• Incompatibility between SQL Server Native Client and Windows 11 25H2 update
• Corrupted or outdated SQL Server Native Client components
• Windows 11 25H2 security policies restricting parameter marshaling in native compiled procedures
• Misconfiguration of SQL Server CLR integration or related services after Windows update

What FixWin checks

• Check SQL Server Native Client version compatibility with Windows 11 25H2
• Verify SQL Server CLR Integration service status and restart if necessary
• Inspect Event Viewer Application logs under 'MSSQLSERVER' source for CLR runtime errors
• Run Windows System File Checker (sfc /scannow) to detect corrupted system files affecting SQL Server components
• Review Windows Update history to confirm 25H2 installation completeness and absence of failed updates

AI diagnostic workflow

• Open Event Viewer and filter Application logs for SQL Server CLR runtime errors referencing parameter issues
• Use SQL Server Management Studio to test native compiled stored procedures with various parameter sets
• Verify the installed SQL Server Native Client version via Programs and Features or SQL Server Configuration Manager
• Check the status of the SQL Server Launchpad and SQL Server CLR Integration services in Services.msc
• Review Windows Update logs (via Get-WindowsUpdateLog PowerShell cmdlet) for any issues during 25H2 installation affecting SQL Server components

Related Windows entities

• SQL Server Native Client component
  Handles parameter marshaling and native compilation support for SQL Server stored procedures.
• SQL Server CLR Integration service service
  Enables execution of managed code within SQL Server, critical for native compiled stored procedures.
• Event Viewer Application Log log
  Contains error entries related to SQL Server CLR runtime failures and parameter validation issues.
• Windows Update component
  The 25H2 feature update can introduce compatibility changes affecting SQL Server native compilation.
• System File Checker (sfc) tool
