Hi,

Recently we have changed an IP address of an Unix server but kept the same
name. Our Unix machines can ping using the host name through Unix DNS
server and returns the new IP. However, from Windows it's still returning
the old IP address through Windows DNS server. We have a mix environment
where all Windows desktops resolve through Windows DNS. Forwarders are
setup to point MS DNS servers to Unix DNS servers.

Do I need to clear the cache from Windows DNS? On the client, I've tried
ipconfig /flushdns but no difference.

Appreciate your .

Does the Unix have a host record in the Windows DNS server?
Are you using WINS?

You'll need to check the Windows DNS and WINS database for records with the
Unix server's name. If the Windows DNS does not have a zone with the Unix
host record, the old IP could still be in the Windows DNS server's cache. To
view the Windows DNS server's cache, use the DNS management console, to
connect to the Windows DNS, in the View menu of the DNS Management console,
select Advanced, that will show the contents of the server's DNS cache. Then
it just a matter of looking in the cache and deleting the cached record in
DNS. Or you could wait one day which is the default maximum cached time.

Thank you very much Kevin.

Shortly after I posted the question, I was able to resolve the name - just
after 24-hr time. I was going to ask how to show cached lookup entries and
you answered it already.
