it seems your workstation is using a local DNS server which assumably forwards internet DNS requests from internal workstations to the DNS server outside (on the internet). why dont you just try to point your workstation's DNS setting to an external DNS server, if it is workable, then the problem is there at your local DNS server; otherwise, i will doubt whether yahoo's DNS server is mad ;)

well its kind of odd.

if i point to an outside dns it works fine.
the problem is that i need to figure out why the internal dns isnt resolving it :(

i think so. what is your DNS server? a dedicate DNS server running a kind of OS such as W2K? or a router with DHCP/DNS enabled? if so, what is its model or type exactly?

I've had this exact problem. There are 2 things that usually resolves the issue:

1) Make sure Round Robin is enabled on your server.
2) Turn off EDNS. This usually fixes the problem if you are behind a firewall (some have trouble EDNS). Checkout this website: http://www.nthelp.com/w2k3/turning_off_edns.htm
