# this is enough to make it all work under Linux clients:
option domain-name "example.org static.example.org dynamic.example.org";

# then i tried the below to get it working for Microsoft Windows XP clients
option domain-search-order code 119 = string;
option domain-search-order "example.org static.example.org dynamic.example.org";
option domain-name "example.org static.example.org dynamic.example.org";

but it still does not work ?
