I have 2 dns servers on our network
server13
       windows server 2008 R2
server18
       windows server 2008 R2

server13 is our primary dns server and everything is working normally
   
server18 has the following problem

1. PING www.google.com works normally = 216.239.38.120
2. nslookup www.google.com 208.67.220.220 works normally
3. nslookup www.google.com returns

          Server:  server18.jbcnet.loc
Address:  10.10.40.25

DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
*** Request to server18.jbcnet.loc timed-out

4. forwarders are
       8.8.8.8
       8.8.4.4
       local isp dns
       local isp dns # 2

5. root hints are enabled and working

6. it has a static ip address pointing to itself as the primary dns
7. it also points to server13 as its secondary dns address



nslookup degug out follows
