Some DNS queries are unsuccessful after deploying a Windows Server 2008 R2 DNS server

Some DNS name queries are unsuccessful after you deploy a Windows Server 2008 R2-based DNS server.  It seems inconsistent but it all depends on the DNS Name being called.  (BMO.COM always exhibits the problem)

Scenario:

1. Clear DNS cache on the server:
   dnscmd /clearcache
2. Run NSLOOKUP
3. Set type=all
4. BMO.COM
   Notice that the first attempt times out.  Repeated attempts will eventually be successful.
5. Workaround:
   Type: dnscmd /config /enableednsprobes 0
