Can't se other computers on the network?

Hi experts,

I have 5 computers setup in a small network with a server. On some computers I'm able to see all the other computers and on some I can't?

Do you have Network Discovery enabled on the computers you can't see the others from? This is a common cause of the issue if not.

Firewall is good. So three is 5 computers and 1 server.

Computer one can see all of them
Computer two can see only 2 or 3
Computer 3 can see none

Then later computer one can only see one computer
Computer 2 will see all of them

It's intermittent and all computers are identical

If computers are on the same subnet, all have IP from the same network , network mask is the same and Network Discovery is enable they should see each others when the are in the same work group or domain. Disable windows firewall and firewall on antyvirus if you have one.
Check ping. and ping IP and hostnames.  Check if you do not have the same computer name on two or more workstations.

Hi Olgierd,

 Ok, what I did notice is that when I put the mouse cursor over the network icon on the lower right of the screen some computers say Network 3 , network 4 . cmcinc.local . so how can I change for all of them to say cmcinc.local? I think that may be the issue. The server says cmcinc.local
