DNS Issue? Can't access Yahoo.com, MSN.com, and other sites...

I have a problem with not being able to reach Yahoo.com, MSN.com, and other
sites on my 2003 SB Server and several workstations. On the server
particularly, it forwards to AnswerFerret.com. On the others, it attempts to
go to www.yahoo.com.net, then goes to the standard IE 'Page Cannot Be
Displayed'. The only thing that has changed is that we went to in-house
e-mail with Exchange 2003 that was built in.

What caused this, and what can I do to fix it? Any info helps!

Can you ping a public IP? if yes, can you ping yahoo.com? also you may want to use nslookup command to check the DNS status. this step by step troubleshooting may help,

YES. Most other sites are accessible. I can even ping yahoo.com and get
their IP's.

I realize this is an elementary question, but how do I 'check the DNS
status' in nslookup? Am I checking the DNS status of my server, or of
Yahoo.com?

In command line type nslookup and try to resolve an internet name thru it.
If it executes without any errors, than your problem is not in your DNS.
BTW, on start, nslookup shows if there is a problem in the connecting to
your DNS.
