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
