anything like that the server comes back saying host cannot be found?
Any pointer would be appreciated

What operating system on the server? What distribution and release?Quote:>They finaly got me back up but now with a different IP address. I

Start with 'uname -a'. If it's Linux, look in /etc/ for a file with a
name ending in 'release' or 'version' - like /etc/redhat-release - and
see what's in that file. That is assuming you have access to the real
/etc/ and are not chroot'ed elsewhere.
You're posting to a Linux group, so if we assume it's Linux, look atQuote:>When I execute commands like host yahoo.com, or whois or ftp or

/etc/resolv.conf
/etc/host.conf
/etc/nsswitch.conf
Also look at the output of the command '/sbin/iptables -L'

1. Dynamic DNS not working with Solaris DHCP/DNS server and win clients
I've got a solaris 9 04/04 box set up with the bundled DNS and DHCP servers but I can't seem to get windows XP clients to dynamicaly register their names in DNS. DHCP seems to work just fine.
I've followed the rather simple doco at http://docs.sun.com/db/doc/806-5529/6jehkcs59?a=view however it still does not work.
This doco covers adding the allow-update directive to the named.conf file, which I've done for local and loop back IPs and then ticking the "Update DNS host information upon client request" check box in DHCP configuration.
When I configure a DHCP domain from scratch and it comes to the section on where to store host names, I choose DNS, I get a popup that says "Unable to manage defined hosts table". I've gone back to "none" then later ticked Edit -> Modify: "Update DNS host information upon client request"....still no updates.
There is nothing loged in the DHCP logs relevant to dns problems.
My named.conf file is:
bash-2.05# cat /etc/named.conf
options {
directory "/etc/named";
pid-file "/var/run/named.pid";
forwarders {
<dns 1>;
<dns 2>;
<dns 3>;
};
forward first;
};
zone "." {
type hint;
file "/etc/named/db.cache";
};
zone "pjama.loc" {
type master;
file "/etc/named/<my domain>.hosts";
allow-update {
127.0.0.1;
192.168.200.1;
192.168.200.11;
};
};
zone "200.168.192.in-addr.arpa" {
type master;
allow-update {
127.0.0.1;
192.168.200.1;
192.168.200.11;
};
file "/etc/named/192.168.200.rev";
};
logging {
category default {
default_syslog;
default_debug;
default_stderr;
};
};
bash-2.05
Any assistance appreciated.
