Newly installed (by full reset) Windows 10 Pro computer cannot connect to Windows 7 computers and Debian SMB servers on the network.
It can see all computers and servers on the network (all computers have same workgroup name), but can connect only to others Windows 10 computers.
I enabled "SMB 1.0/CIFS Client" in Windows features. "Enable NetBIOS over TCP/IP" is checked.
If i do from cmd:
nbtstat -a myservername
it works and shows server information
Ethernet:
Node IpAddress: [192.168.0.32] Scope Id: []
NetBIOS Remote Machine Name Table
Name Type Status

MYSERVERNAME <00> UNIQUE Registered

MYDOMAIN <00> GROUP Registered

MYDOMAIN <1E> GROUP Registered
MAC Address = 00-00-00-00-00-00
but
net view \\myservername
gives error "System error 53 has occurred. The network path was not found."

Thanks to user gravity comment, i used Wireshark. In Wireshark there was "SMB2 Negotiate protocol", then "SMB2 Session setup", there Windows 10 was stopping connection after server offered him to connect using Guest access.
So i found this Microsoft article https://support.microsoft.com/en-us/help/4046019
Turning
"Enable insecure guest logons"
in group policy resolved this issue.
