Windows 10: Lost connection to network NAS's on one PC. Works fine on another

Windows 10 ver 1909.

I can see and connect to two different NAS devices on my network from a laptop, but cannot from PC now. I tried to insure Network settings (Sharing settings, SMB, IPv4 NetBios, etc) from laptop were the same on the PC, but nothing worked. Seem to have the same Win 10 updates.

Cannot connect to any devices via \\sharename in Explorer. One NAS icon does show up in Explorer Network devices list, but clicking on it gives a connection error. All mapped links are now broken as well. Thanks in advance for assistance!

NAS connected to local network not showing up on some PC's

Like so many, I have multiple PC's on my home network plus NAS, printers etc. Regardless of wired or wireless connection, everything works fine and all networked devices including NAS is visible as it should - except one! This particular PC, shows all
network devices, except the NAS. From an OS perspective this PC is identical to all other PC's on network and runs latest version of Windows 10 Home. I have tried different methods that some folks suggested, including login in as an admin, on the internet
but no joy. All other PC's on network, has no issues in reading or writing to NAS.

Can someone help to fix it?

 

Lost network connection to QNAP NAS after Windows 10 upgrade


Hi folks,

I was apprehensive about Windows 10. I know this because the upgrade icon stated for a while now that it was ready to download and install - but I wasn't. I was quite content with my Windows 7 Ultimate 64-bit OS. Unfortunately, yesterday in a particularly good mood I installed Windows 10.

This morning I found out the sound didn't work. Fixed it after half a day of tinkering. Also found out that the NAS QNAP-TS412 no longer exist under my Network section. I tried but failed to find a working solution. I'm hoping someone might have a suggestion or idea that I can try. I'm no techie by any means so please have patience and bear with me.

I tried mapping the network drive, surprisingly enough I can see in the Drive field that my folders still exist in their corresponding drive letters, but they don't show up under the NAS! When I attempt to connect them I get a Network Error message, specifically Error code: 0x80070035. The network path was not found. Windows Network Diagnostics suggested I turn on the computer or device and connect it! Haha. I have an barebone PC NUC with a LAN connection to the NAS and it read fine. No points for guessing the Windows 10 was responsible. Help!

I have attached a text file of a Speccy summary of my PC. Thanks in advance folks.

 

PC cannot see other computers and nas drives on network

I have a laptop in the network who has developed a very strange fault and I can't get to the bottom of it.

The network is a 5 pc, 3 printers and 2 NAS drive set up all connected through ethernet cables.

All other PCs can see everything fine and are stable.

The problem PC is on the network, Has an IP address, can connect to the internet and no other issues beyond the network connections in file explorer doesn't show the other PCs or the NAS drives.

HOWEVER!!!

The laptop can ping the NAS drives(and I have added the shortcut to quick access as a workaround) but cannot ping other PCS on the network and they cannot ping it but does show up on the Broadband router connections list and a Belarc scan from another PC on
the network.

The laptop in question is

Win 10 build 150(something)

Latest updates

Latest LAN driver etc etc

I have reset the network connection through Win 10 as well.

Any clues?
