Unable to access a Windows share (able to ping)

Hi everyone, I am having weird network issues that I cannot figure out. I have a Windows 11 machine that is hosting a shared folder, and requires username/password to access. From Windows 10 machines, I can access it. From a Windows 7 machine, I used to be able to access it fine, but after a router reboot, I cannot access it. There was one time I was able to access it only if IPv6 was enabled (and only via WIN11-NUC and not IP address), but since I disabled it on the router, it stopped working. I ran `net stop workstation` on both machines with no resolution (found the idea here: Mapping network drive System error 64). Also, from the Windows 11 machine, I can access the Windows 7 share.

PS C:\Users\?> tracert 10.0.0.117

Tracing route to WIN11-NUC.lan [10.0.0.117]
over a maximum of 30 hops:

Trace complete.
PS C:\Users\?> nslookup 10.0.0.117

PS C:\Users\?> net use \\10.0.0.117
System error 64 has occurred.

The specified network name is no longer available.


I also have issues from a Linux machine. I can ping it fine. I used to be able to mount it just fine, but now it returns this error. I am able to mount a shared folder from another Windows machine.

?@ubuntu-media:/mnt/share-nfs$ sudo mount -t cifs -o ro,username=?,password=? //10.0.0.117/share-nfs /mnt/share-nfs
[sudo] password for ?:
mount error: Server abruptly closed the connection.
This can happen if the server does not support the SMB version you are trying to use.
The default SMB version recently changed from SMB1 to SMB2.1 and above. Try mounting with vers=1.0.
mount error(112): Host is down
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

Do you have any ideas what is going on? I don't believe nor recall that I did any network reconfiguration that would have caused it. Maybe I should get rid of Windows 11 and replace it with Windows 10 because Windows 11 feels really slow. Thank you.

I assume you are trying to access your computer using File Explorer > Network. Since that is problematic with Windows 10 and 11 I don't depend on that. I created a folder on one computer's desktop called My Network. In that folder I placed shortcuts to each computer on my network. A computer's shortcut is \\ + ComputerName. For example, the shortcut to computer DarkMatter is \\Darkmatter. When done I copied that folder to the desktops of all my computers.

Thanks. I still have the problem when I try to create a shortcut, I still can't point it to `\\win11-nuc` or `\\10.0.0.117` because it will not connect.

Good news update -- I decided to do a `Network reset` from the Control Panel and it works again :)
