Win10 Pro Computer Can't Access Ubuntu Server Shared Folders on LAN - Samba, Ping Works, Error

Hello.
I have a problem with one computer (WIN10 PRO).
I have about 30 computers on the network that have shared network folders from the server (Ubuntu server + samba). On this one (new) computer, I can't connect to shared folders. Ping works but if I enter the address in the bar \\ 192.168.14.100 it shows "Windows cannot access \\ 192.168.14.100". Diagnosing has no solution.
I was looking for possible solutions but nothing worked.
What I did?
- system reinstall
- adding a password to the user
- enabling guest account
- enabling "SMB 1.0 / CIFS file sharing support
- setting the network to Private

I will add that the computer is assigned to the right workgroup, has the option of network discovery enabled and can see the entire network environment (unfortunately I cannot access the shared printer). Password sharing is disabled ...

Does anyone have any idea?

Hello,

And can it communicate with other computers?
Is there a firewall such as ESET or something?

Other ping computers receive but cannot connect to them through the network environment. After double click I get information about the lack of access ...
As for the firewall, it is a clean installation, without av, and I disabled the firewall in windows defender.

Are the "Computer Browser" and "Workstation" services on this computer running?

Yes, both services are started and set to Automatic.
It is interesting that the internet works properly (I browse websites, download files). Something is online ...

/// edit

When attempting to map a network drive (although it cannot find it through the address bar), the following message appears: "Unable to create mapped network drive due to the following error: You do not have access to this shared folder because organization security policies prevent access by unauthenticated guests. These policies help protect your computer against dangerous or malicious devices on the network. "

wtf ???

And if you share a directory publicly on one of these 30 computers, then you can't deny access?

I cannot enter this directory. Refusal.
I can see computers on the network but I can't access any ...

Workgroup created, name assigned to all equipment the same?

In the first post I wrote that the working group is set up correctly ...
In addition, it does not have to be the same on all hardware for the computer to see the server (it is enough on the server and the computer that is to see it).

@ turek77
Maybe some permissions are missing to access the site / directory?
Check on computers where it works and add what is missing where it does not work.

And if you create a directory on this computer and make it available, then you can get to this directory from other computers?

Hmm, maybe at the first connection you entered and remembered the password / user?

See Control Panel -> Credentials Manager -> Windows Credentials
Check if you have an entry for IP 192.168.14.100 and if necessary edit or delete it.

@pioflo in fact there was nothing in the credentials ... I added the server ip and login and password and found ... The network drive came back but I still can't connect to the shared printers ... Other computers do it without a problem ... I can see the computer sharing on the network but I am denied access ... I was looking at another computer and there is no additional credentials ... Anyone have any idea? Network discovery is on ...

aaa and when trying to connect to the computer sharing the printer I don't have a password prompt ... I just can't access. On the computer sharing everything is set up as it should be because 4 computers use its printer ... The fifth I just connected in 5 seconds ... And this damn little can't ...
