Free Way to Fix Microsoft SQL Server Error 4014

SQL Error 4014 is often related to Microsoft’s Scalable Networking Pack (SNP) features, which aim to improve network performance. However, these features can sometimes cause issues with SQL Server. The three main components involved are:

• TCP/IPnetsh int tcp show global
• Chimney Offload: reduces CPU load by shifting network tasks away from the processor.
• Receive Side Scaling (RSS): spreads network traffic processing across multiple CPUs.
• Network Direct Memory Access (NetDMA): helps transfer memory data more efficiently.

Steps to Disable SNP Features:

1. Firstly, open Command Prompt as an administrator.
2. Then, run the following command:
   

   • netsh int tcp show global

3. After that, disable TCP Chimney Offload:

   • netsh int tcp set global chimney=disabled

4. Then, disable receive side scaling (RSS):

   • netsh int tcp set global rss=disabled

5. Now, disable NetDMA via Registry Editor:

   • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TCPIP\Parameters

6. Lastly, restart your system and check if this error has been resolved or not.

Additional Troubleshooting Tips

If the error still appears:

• Make sure all SQL Server services are running properly.
• Also, check the SQL Server logs for related warnings or errors.
• Otherwise, update SQL Server to the latest version and install any missing patches.
• Moreover, restart the server to rule out temporary glitches.
• In some cases, rebuilding system databases may be necessary (advanced users only).

If you are facing SQL Server Error 4014, the manual method works. But, they require technical knowledge. Furthermore, if done incorrectly, you might affect the server’s network performance or risk data issues. That’s why using the alternative mentioned below is an effective and efficient choice.
