LAN Configuration Issues: WIN10 Updates, TP-Link 24-port Switch, TD-W8950N Router, CAT5E

Hi, I haven't been able to cope with the LAN configuration for a long time. I have the impression that my problems appeared after one of the WIN10 updates. So, to the point: I have a LAN network, 10 workstations connected with a CAT5E twisted pair to a 10/100 switch (24-port unmanaged TP-Link). There are also 4 network printers connected to this. In addition, a gateway to the world in the form of a TD-W8950N router (soft unbranded), to which smartphones connect to WIFI from time to time. Separation of IP addresses is done by the router (stations have automatic addresses set, they are rigidly assigned in the router by MAC addresses). The problem is with the visibility of individual stations in the LAN (resource sharing). Different computers see different computers, not all of them have access to shared resources, i.e. from computer X I can see computer Y and Z, and from computer, e.g. Y, I can only see computer Z - I find no logic in it at all. I would like to add that the internet works at each station without any problems.

-All stations are loaded with Windows 10 64bit, in various configurations (Home and Prof.), one station is 32 bit
- Same homegroup set up everywhere
- the same type of network (private, i.e. trusted)
- password protected sharing is disabled everywhere
- network discovery enabled
- file and printer sharing enabled
- same encryption (128bit)
- I have started SMB1.0 / CIFS file sharing service everywhere (Control Panel> Programs and Features> Turn Windows functions on or off)
-All shared resources are made available to "Everyone" (not specific users).
- only Windows firewall and Antivirus are installed on all stations
- the network does not have a hardware firewall
-computers, although they are not available in the "network neighborhood", ping each other
-some computers can be reached by typing its address (or name) manually, although the file server is not hidden (CMD> "net config server" shows that it is not hidden)

I will also add that:

- resignation from distributing addresses rigidly by the router does not solve the situation
- the problem exists whether all stations are turned on or only some stations (I tried to disconnect individual stations to see if it helps)
-disabling the firewall does not help
- the situation is strange because there are stations that are visible, but refuse access to resources, and there are stations that are not visible, but do not deny access (then they should be called after the address or a prepared shortcut)

He realizes that one of the solutions is to put NAS in the network, but this creates other inconveniences, characteristic of the way of working in the office.

I will be very grateful for any suggestions. It seems to me that I have described the configuration and the problem in detail, if you have any questions, I will be happy to answer.

Regards, Bartek

I've had something similar in one network for about a month. So far I haven't found a solution.
Visibility is there, it willingly disappears, sometimes it comes back.

Do you connect to the computer by its name or by IP?

As I wrote, one sign of the problem is that computers are not visible in the 'network neighborhood'. However, some of them can be called either with a prepared shortcut or with a manually entered address. Then, it doesn't matter whether it calls them with the IP address (which are assigned by the router rigidly) or with the computer name, if the computer can be called in both ways.

Hello. I have the same problem. I wanted to copy files (pcb kicad projects etc.) from my laptop to a better pc connected to the same network, there is a bit of it and connecting something to the usb even though I have a 30GB disk is annoying and I value peace the most. I used to copy huge files to ps3 via a network cable but in win 10 even ftp is hard to set up, it doesn't work for me. After the update, sharing does not work at all, no labidok is visible on the pc. Could it not be like on an android that the program provides a folder and everything is fine? The only way out is to open the cap and pull out the disk because windows is so great that we have a system that is still in beta .. Does anyone have a golden mean for this crap?
