Linux client updating Windows DNS dynamically

I have to build a number of Linux workstations (Redhat Enterprise WS3 or WS4) which will get their IP address using a Windows DHCP server (Server 2003 probably). I can't see a problem with this.

I have to then update the Windows DNS server automatically with the details. I have no experience of this.

Does anyone have any straight forward documentation which will help me configure DNS updating of a Windows server from a Redhat client please.

Thanks
David

Assume that your network device in Linux called eth0, then
make sure in the file
/etc/sysconfig/network-scripts/ifcfg-eth0
has this line:
-----------
DHCP_HOSTNAME=<hostname>
-----------
Then the DDNS feature on Windows DNS server will add the IP address + hostname of Linux client into the DNS database automatically.

As my experience, RHEL WS3 doesn't have this line in /etc/sysconfig/network-scripts/ifcfg-eth0 but RHEL WS4 should be ok.

Thanks for your comments. However Redhat is the recommended OS for the main apps so I can't change that, and I am also forced to use Windows based DHCP and DNS servers which are supported by another service provider and are out of my control.

Thanks for the advice on the ifcfg-eth0 file. Our kickstart writes this file for us. Looks like I might have to re-write some of the kickstart process.

Things are on hold for a week or so until I can get hold of a suitable network on which to test. I'll get back to you.

Thanks
David
