color=#0000ff size=2>You have recursion disabled on your abc.com server, and I
believe that is preventing your query from succeeding. My
understanding is that the contents of the root hints file are not stored in the
server's cache (which means, I think, that they are not themselves returned in
response to queries for those records). Since you have recursion disabled
on abc.com, it is never using its root hints to query your root server
(rootns.man) for the NS and A records for the root zone (which sounds
obfuscated, but it is done that way because the root servers themselves have the
most current list of servers for the root zone).</FONT></SPAN></DIV>
