My network places problem - Help

in Off-Topic
I have a domain controller with 36 PC's and 5 servers.
Everything is working fine you can access mapped drives RDP into all pcs the only issue I have
is when accessing all the clients through my network places and then entire network I can only see about 10 clients listed.
Is there something I need to configure on the missing clients.
My overall aim is to see all c drives from my machine using the following from run
\\computername\c$
however this only works on the clients listed in my network places.
What am i missing ????

Is the server service enabled and running?
Another thing you can try to take out name resolution completely is using the IP address\C$
Might there be a firewall blocking that port?
Recent: 11/2019 - RHCSA (RHEL 7); 2/2019 - Updated VCP to 6.5 (just a few days before VMware discontinued the re-cert policy...)
Working on: RHCE/Ansible
Future: Probably continued Red Hat Immersion, Possibly VCAP Design, or maybe a completely different path. Depends on job demands...
+1, this would be my first thought and has caused some issues in the past. (XP or 3rd Party Firewall)
Here a quick link you can look at that may help:
