Unable to resolve to internal server from Surface Pro

I currently have a surface pro in my possession running Windows 10.   The wireless network adapter is connected using DHCP (both IP and DNS) as another laptop to the same internal network.   I have disabled all VPN clients and the internal wireless nic on the surface pro is getting the correct internal address.    

However when I attempt to ping the dc controller which is on the same internal subnet on the working machine the ping returns the internal local address of the DC.  When I attempt to ping it from the surface pro its attempting to ping an external dns with an external IP constantly and I am unable to unc to the server because of it.   I have flushed and re-registered the DNS rebooted reconnected to the internal WIFI with no luck.   Any thoughts?

I am unsure where to check if there are any persistent routes that are setup in windows that may be causing this.
Andrew N. KowtaloSupport Center EngineerAuthor Commented:
So performing an nslookup it gave me to returns internal and a non-authoritative which shows the incorrect domain name and incorrect IP to which the ping is pointing.
Cliff GaliherCommented:
Post an ipconfig, the results of a ping test, the results of an nslookup to start.

It is unlikely a static route issue as that would not cause ping to returm an external address. That's something else.

Its the NSlookup returning 2 results.   I need to delete the non-authoritative answer that's pointing to the external domain and IP
Cliff GaliherCommented:
That'll be on your DNS server. Not the client. And would usually impact both machines.  But without seeing the output, it is tough to be more specific.
Andrew N. KowtaloSupport Center EngineerAuthor Commented:
Found it.  If it do an ipconfig /all its showing a DNS suffix search list pointed to that domain with the primary DNS suffix pointed to the correct domain.
Andrew N. KowtaloSupport Center EngineerAuthor Commented:
I need to figure out where the primary adapter showing that information is and shut it off
Andrew N. KowtaloSupport Center EngineerAuthor Commented:
It was under the advanced setting of the DNS to append to those 2 external domains.  I deleted them both and rebooting lets see if this works.
