[NTLUG:Discuss] Any DNS gurus out there?

[LEROY TENNISON]

If a DNS server is trying to resolve a name for a client and:
      
   Gets a list of referrals from      another DNS server (assume an Internet client requested www.google.com and      the DNS server doing the resolution asked a ‘.com’ DNS server      for an authoritative source for google.com).
   And the first referral in the list      is down

     What happens?  Does the resolving DNS server try the next referral in the list or does it give up and tell the client “can’t resolve name”?
