DNS Question

I don't pretend to be an expert in DNS ....

But I've got a dual-NIC server, one side pointing to the outside world, the other inside.  The default gateway points externally, as does the DNS.  If I do an NSLOOKUP on the box, I jump to the outside (142.77.1.1) UUNet outside address.  But if I type PING and put an internal DNS name in, it knows to use my internal DNS.

My question is how does it know to go external or internal, especially when my default gateway points outward.  So if I work for xyz.com, and type ping donald.inside.xyz.com it resolves the IP on my internal DNS, but if I type ping google.ca it resolves outside ... where is that decision made???

Thanks!

If you have a forwarder setup, it will ask the server listed where the dns entry is. I'm not 100% sure how you have your system setup, so I can say for sure on your's, but that's the general idea. If you right click on the DNS server in the DNS snapin go to properties and in those tabs you will find the forwarder section.

CDCOP - I was looking more for how the local station determined the route.
