Exchange 2013 and Internal DNS Sending Mail Issue

Here is my scenario.
Exchange 2013 sitting on a 2012 Server in a domain.
Has regular LAN IP address, and is single email server for a company.
Uses Internal DNS of PDC in domain.
Having an issue with only 1 client when sending email.
So on the exchange box, i did an nslookup and got their email server name, which from the same exchange box, i can ping.  so I also did a tracert and a telnet to that email server on port 25 and it all works.
But when I check the queue viewer app, it tells me unable to connect, unable to resolve DNS name.  So i scratched my head, and changed the DNS IP to the ISP dns rather than internal and it works.  Only problem is all internal clients on outlook stop working, so i changed it back.
So i try another internal DNS server and no luck either.  I dont understand how this is possible.  If i can resolve in a command prompt and via telnet, why doesnt the exchange send connector resolve it?  
Ill take any suggestion...

Didnt know you could set those settings in exchange, thought it was driven by the NIC.
