Windows 10: How to completely disable SMB in Windows 11

I have a QNAP NAS that I've been connected to via SMB at some point in the past. I later removed those SMB connections to the NAS, but at some point my NAS started blocking the IP of my PC because it was still sending login requests via SMB using my Windows account, and those login requests were failing. I could not get the requests to stop, so I decided to disable SMB in my Windows. I disabled SMB v1, v2, v3 and SMB Direct and still my PC is sending SMB requests to the NAS.So the NAS is still blocking my PC IP every few minutes.I can see in my PC resource monitor that the process System is se

SMB Share Problem Confounds IT Guy!

Have an existing LAN with a Windows 10 PC and a Windows 11 PC that both can access an SMB share on the network. I replaced the Windows 10 PC with a new one running Windows 11. The new Windows 11 PC cannot see the SMB share.

1. Have confirmed that all SMB protocols are enabled on the new PC.
   
2. Have disabled the third party firewall and the Windows firewall on the new PC; did not change the result.
   
3. Have disabled the anti-virus on the new PC; did not change the result.
   
4. Have disabled all items in Startup Apps; did not change the result.
   
5. If I boot in Safe Mode w Networking, it works. I can see the SMB share.
   

So it works if I boot in Safe Mode, but it doesn't work booting normally with all Startup Apps disabled.

What am I missing? What else happens in Safe Mode beside Startup Apps being disabled? What's blocking me?

Confused

 

Windows Updated(16299.309).KB4088776 Restart is required to complete.

Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

Thanks for the suggestions and for the time to respond Best regards.


And thanks for the tip of that program, I'll have it on my list.

 

How to solve problems with accessing, discovering and connecting to NAS with SMB connection from Windows 10

I am experiencing difficulties with accessing, discovering and connecting to my NAS with SMB connection from Windows 10.

I have tried most of the solutions suggest on the Web, but avail, none of them worked.

• Enabling SMB v2 and restarting
• Checking SMB v1 in Windows components is ticked on
• Etc.

It seems that Microsoft has broken something though their patches

If anyone can supply me with a permanent/ final fix,
not workaround, please post it here.
