Strange LAN Problem

[thundertech]

I have a WEIRD one here. I am trying to set up a small renderfarm in my room and I can access shares that I've set up on my server, but I can't ping the thing. The only way that I can access the server is to open Run and then type \\SERVERNAME, then I can upload to shares and download from them and do whatever else, but Windows simply can't find it any other way. I've turned on network discovery on all of the computers in the setup and I've even played with Windows Firewall to try to ensure that it isn't blocking packets that are required for Network Discovery. I believe the problem is on my server, because all of the other computers on my LAN can access one another without any problems. If you know how to delve into Windows Server 2008r2, then please dump some knowledge on me here so I can get this done.

The Setup: Rendering Server (Windows Server 2008r2), Laptop (Windows 10), Desktop Workstation (Windows 10)

Thank you for any help mes frères!
