New Windows 10 PC will not connect to server 2012 r with server name

I have a new windows 10 pc and I am trying to connect to the server with it. I can get to the server by IP address but not with the server name, in this case it is \Server-01. It is telling me that the dns server is not responding or incorrect. I have several other PCs connected and working on this network to the server. All of the services are running and I can ping \Server-01 at command prompt. I have flushed dns etc. The other day I had this working and now it does not. There was a third party on this trying to install software from the server and then I now have this issue. I am not sure what they did and do not know what they might have changed. The install of the software was unsuccessful and called it a network issue. To go further they could not install the software off the server with the server name so they started using the IP address to the server to see if that resolved the install. That is when I believe it stopped communicating with the server name. Any help would be appreciated. Thank you..

    You will need to describe your network environment.

    For example, here at my home I have a WIFI router that connects to the internet. All of my PC's and test VM's use DHCP. When the PC boots, DHCP acquires an IP address from the router. The NIC's are set to "Register this connections address in DNS". When I run NSLOOKUP against a name or IP address, it displays the PC's IP or it's name. All of my PC's use the WIFI router as the DNS server. (The default from DHCP.)

    There was a third party on this trying to install software from the server and then I now have this issue. I am not sure what they did and do not know what they might have changed.

    Your server/desktop/network admin should have been looking over their shoulder to watch what they were doing and verify that the decisions that they made were consistent with your organizations polices and help them work through any issue that they might encounter.

    Is this a home network? Small business network? Do you use Active Directory? Who provides desktop and server support? Have they investigated this problem? What DNS servers do your machines use?

    Sounds similar to my home network. Open a command and run "ipconfig /all". Here's what I get.

    Wireless LAN adapter Wi-Fi:  
      
       Connection-specific DNS Suffix  . : home

       NetBIOS over Tcpip. . . . . . . . : Disabled  
    

    Are the addresses for DHCP Server and DNS Server in your results the same IP address? My PC has an IP address of 192.168.1.3. From the command prompt run an NSLOOKUP on some of the IP addresses on names of your PC's, Do any resolve?

    This is very similar to this post that I helped another user with. In his case his router's DNS did not register his local PC names. We verified that all of the Network Discovery services were running as DSPatrick has pointed out. You might want to look through that post because the troubleshooting steps are the same.

    You have a problem similar to the other user. You can't register 192.168.0.23 because every other Charter Communications (TWC) customer could have that address in use.

    In my opinion, your router is not configured properly, but that may be a "that's how this model works" situation. My router provides DNS so that my local machines can get their name registered and resolved. If I browse Yahoo.com, then my router will query external (internet) DNS servers to get the IP address.

    Your PC's are going straight to the internet DNS server and can't resolve the local names.

    Try running the Powershell script in that other post and see if that fixes Windows Network Discovery.
