My Windows 10 PC is unable to access a shared folder of my NAS.
The NAS does not appear under
Network and when I try to enter the address
\\<ip> I just have an error message "Windows cannot access \\mynas".
The NAS is correctly listed and I can browse the folders from an Android phone using several apps like Ghost commander or ES File manager.
I tried disabling the firewalls on the Windows 10 PC, it does not change anything. I have checked all the "network share" settings and everything seems ok.
So I did a packet capture using wireshark. And what happens is that everything goes well, at the start. Windows retrieve the NAS ip address from its netbios name and start the protocol negotiation. But as soon as Windows received the "Negotiate Protocol Response" from the NAS, it closes the TCP connection. Windows then does a 2nd try, but the same thing happens.
The next packet is a TCP RST,ACK from Windows
