I am not sure where I make mistake. I have two almost identical Windows Servers 2012 R2 installations – servers A and B. One server A, I have setup a shared folder. I have verified that I can connect to this share folder from my Windows 10 using UNC path \\IP\Name. I can see files a folders, read them …
However, if I want to do the same from server B, it always fails. When I try "net use \\IP" or "net use \\IP\Name" on server B, where IP is address of A, I get:
System error 53 has occurred.
The network path was not found.
If I do the same on my Windows 10 desktop, I get success and can work with the share folder and map it.
And I am not sure what I have not tried yet, but I have checked these:
1) network connection properties of server B, if server B has enabled Client for Microsoft Networks – yes; if server B has enabled File and Printer Sharing for Microsoft Networks – yes
2) I have tried advanced properties of IPv4 -> WINS tab -> Enable NETBIOS over TCP/IP (made no difference to default, both A and B have static IPv4)
3) enabling Network discovery and allowing its firewall rules in firewall.cpl + same for File and Printer Sharing and their rules; again made no difference
What am I missing. How can I access shared folder from Windows Server 2012 R2 acting as client.

After trying several different machines I have realized that
my hosting is OVH and they block outgoing connections to ports 139 and 445
If this is also your case, use IPv6, they do not block it and it works. If you are having problems with new Cloud 2016 VPS - they do not have IPv6 at all, use https://www.tunnelbroker.net/ to get IPv6 connectivity.
