This really is a Windows problem.  Try turning off the DNS Cache client
in Services (make it manual).  The cache is probably causing you
problems. If you are using dig and nslookup from the Windows BIND
kit, it does not use the same resolver at the other Windows clients. It
uses the BIND resolver. Be careful that you are using either Microsoft's
nslookup or BIND's nslookup.
