asked on Unable to reach certain websites DNS issues
Today I started having issue with my DNS resolution and can't quite find out how to fix this issue. I have two DNS servers on my network and the primary domain controller cannot reach UPS.com but the secondary server can. On the primary server I can reach most sites but when it comes to UPS it cannot. I have restarted the server and checked the DNS settings on the NIC and all looks good however I am unable to reach UPS on that computer and since this is the primary domain controller my users cannot access the site either.
What can I do to find out what is causing this configuration error

Flushed the DNS and restarted both servers. The primary server can get to the UPS website but the secondary cannot. When I ping the ISP DNS servers the first server times out half the time and the secondary never times out. Could that be the issue? It really doesn't explain why one server can reach the same site while the other cannot.

Next make sure that the DNS server is using itself as the primary DNS and the secondary server is the other INTERNAL DNS server. Next verify that the forwarders setup are valid and responsive. Good luck!
