Thank you very much.  I tried what you suggested and it seems that these two servers work perfectly. In fact, I can simply set my DNS to these two servers and have the internet names resolved without any problem. The only reason I run my own DNS server is to resolve the intranet names.


~$ dig @216.171.238.66 hp.com
