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.

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.

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

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.

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.

I need to figure out where the primary adapter showing that information is and shut it off

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.
