Windows 7: Issue - Wireless computers can access shares, main wired one can't

Windows 7 Ultimate 64bits
Issue - Wireless computers can access shares, main wired one can't


I'm just new on the forum and hopefully, you'll be able to help me fix this issue.

It's an issue I've been having for some time but could find a workaround but the arrival of a NAS changed the matter.

Here are the actors:
1 A modem/router allowing me to connect to the internet
2 My main wired computer connected to the router (ASH)
3 Another computer connected to the wireless network (either my other desktop in the living room or my Asus laptop)
4 My brand new Synology NAS connected to the router through a cable (AVALON - also the name of the wireless network, shouldn't be a problem though, wired network has the default name and I don't know if I can change it on the router)

The issue was, and still is, that wireless devices can access the shares on my main computer, but my main computer cannot access the shares on other (including the NAS).

On the laptop, under network, every device appear and is clickable without an error allowing access to the shares.
On the main wired desktop, I do not see the nas but I see the laptop and the main desktop itself but when I click I get an error (see attachment).

Also, while not seeing the NAS "share device" (computer icon) I see both the nas device from which I can access from the wired computer through the web interface by double clicking on it (see second capture).

I've searched the web and tried a bunch of fixes, to no avail. The problem is still there and I cannot access my nas through my main wired computer.

Any idea what the problem is and, more importantly, how to fix it?

Thanks in advance for any clue...

OK, here's some more info:

I've tried connecting with my laptop with the same cable (replace the main desktop with the laptop), and I see everything: the local machine share and the NAS.

So this is definitely something on the main desktop's configuration.

Any way to reinitialize the network config on the computer without reinstalling the OS?

Found the solution.

From here:

I suspected the problem had to do with corruption or misconfiguration with the "Client for Microsoft Networks" (Workstation Service) and "File and Printer Sharing for Microsoft Networks" (Server Service) add-ons to the Windows network stack. You see these items in the advanced configuration of your network adapters.
What I did was uninstall both protocols and reboot. After the reboot, I opened an elevated command prompt (Run as Administrator) and ran the following commands:
netcfg /c c /i ms_msclient
netcfg /c s /i ms_server

The first command reinstalls the "Client for Microsoft Networks" piece and the second the "File and Printer Sharing for Microsoft Networks" piece. After rebooting, I rejoined the HomeGroup and was able to browse and write to my file shares.
Hope this helps!
