at global, I have configure:

class "windowRIS" {

     match if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient";

    option vendor-class-identifier "PXEClient";



now on one subnet I want the server as

I have done:

   subnet netmask {
        option broadcast-address;
        option routers;
        pool {

            failover “failover”  
            deny dynamic bootp clients;

but, the client still insist to use, what I did wrong?

any comments will be appreciated

thanks in advance
