Hi

I am one step forward, kind of.

If I put on debug with my nslookup I get this output.

 > www.sun.com
Server:  ns.accesscomputing.co.uk
Address:  213.128.229.177

;; res_nmkquery(QUERY, www.sun.com, IN, A)

Got answer:
     HEADER:
         opcode = QUERY, id = 7013, rcode = SERVFAIL
         header flags:  response, want recursion, recursion avail.
         questions = 1,  answers = 0,  authority records = 0, 
additional = 0

     QUESTIONS:
         www.sun.com, type = A, class = IN

*** ns.accesscomputing.co.uk can't find www.sun.com: Server failed

The domain name accesscomputing to the address I am trying to look up so 
it is trying to find www.sun.com.accesscomputing.co.uk.

Is there anyway to stop nslookup doing this?  Is it a new 'feature' as I 
am sure this didn't used to happen.

Dig is still failing also:

; <<>> DiG 8.3 <<>> www.sun.com +debug

;; res options: init debug recurs defnam dnsrch
;; res_send()

;; WHEN: Mon Jul 18 10:53:28 2005
;; MSG SIZE  sent: 29  rcvd: 29

I get the message 'server rejected query:' in the debug output.

Anyone got any pointers.

Many thanks

Lara
