Hi

For the answer to be coomplete, I will require the following:
a. Step by step instruction to create a DNS cluster between Linux and windows.
b. Whatever batch file or script needed to acomplish automatic updating.


* Current situation

six Linux servers and one windows server, three are installed with
CentOS 4 and cpanel for shared hosting, one is installed with 2003
server and Plesk 7.5, the other three are installed with Shrike (RH9)
and cpanel "DNS only".

Currently the "DNS Only" are configured as cluster and the shared
hosting servers are replicating changes to the "DNS only" cluster,
this is done with cpanel tool by implementing RNDC.

The plesk windows server was installed with bind also.
In plesk there is an event manager documented here:

If you require any additional info I'll be glad to provide it.
Ilan
