I had a similar problem a few years ago.  The problem was one of:
- Windows not properly appending the domain name to a plain host name
   (i.e. a non-FQDN)
- the Windows DNS cache
   (see ipconfig /flush or similar)
- misunderstanding that ping is different from nslookup/host/dig
   (ping uses the entire name resolution service which may include
   %windir%/system32/drivers/etc/hosts and others whereas nslookup
   uses only strictly DNS)
