If I'm understanding you correctly, you have a setup where all the ddns info is handled by the linux DNS server, then you want to have windows slaves of that information, and lastly you want the clients to use the windows DNS servers as their DNS?

That is easy to do, if microsoft DNS behaves, which I have no idea about. Set up slave zones on all the microsoft computers, and have the master be the linux server. Make sure you configure both sides - every slave should know the address of the master, and the master should have the addresses of every slave listed in its named.conf.

This seems like a poor configuration. If the linux server is doing ddns for the clients, and it also runs a functional version of named, I don't know why you'd need 4-5 slaves. If they are remote locations, I'd run a separate ddns server at each location, that feeds the data upstream if needs be. Still, whatever your reasons are for doing this, it is no harder than setting up the slave zones on the microsoft boxes.

Peace,
JimBass

now for each department viz electronics block ,mechanical block. library block ,mba block we want that there should b different servers which handles d request of clients in each block.
so we r trying to set different servers in each block which are slave server and we want to connect them to linux server.....

sir from ur response, i want to know that how can we link different windows ddns at remote locations to our main linux ddns server....
sir we want that all the clients at different locations will b handled by their respective windows ddns server but their entries should also store in linux ddns which is a main server.....
is this a good way to do this or is there any other convenient way...

I have no idea if Windows supports ddns functionality. I know that ISC (the people who make BIND) have written Windows ports of all the recent versions of BIND, so you "might" be able to get all the windows servers running BIND, and then forwarding their ddns info to the main server, which would be done in a traditional master slave environment.

Something like this:

Install BIND and DHCP on the windows servers (electronics.college.edu, mechanical.college.edu) to get the ddns happening in an environment that the linux box can deal with. Make each subdomain master for its particular subdomain, and slave the "boss" server to each localized master.

The named.conf file on the master would have something like this for each child zone:

Code:
zone "electronics.college.edu" in {
        type slave;
        file "electronics.college.edu";
        masters {10.0.1.1;};
};
zone "mechanical.college.edu" in {
        type slave;
        file "mechanical.college.edu";
        masters {10.0.2.1;};
};
And then you'd obviously change the IP and domain names to reflect what the zone name and IP address truly is. For the generic college.edu zone, that would be defined on the boss, and the generic subdomains (not any of the 7 or 8 subdomains run off the windows machines) would be defined by a wildcard (*.college.edu) at the end of the named.conf on the master.

I have no idea if this can be done with microsoft DNS/DHCP, but I suspect that it could be, again by making the apparent master the slave to the local masters. You could google for how that could be done. I know it could be done with ISC DHCP and BIND.

If anything is unclear, write back. We're approaching the Thanksgiving holiday in the US, so I won't be around all that much, but I'll write back when I see your question.

Peace,
JimBass
