We are trying to issue multiple domain search suffix from our client machines using DHCP on a OES 1 linux server
I have searched the internet and convinced this the correct sysntax
We have added the following to the /etc/dhcp.conf

option dns-domain-search-list code 119 = string;
To the global options

option domain-name "a.b.c.d";
option dns-domain-search-list "xyz";
To the scope options

But all we are seeing on the XP client machines is

Primary DNS suffix: a.b.c.d
DNS suffix search list: a.b.c.d
No xyz

a.b.c.d in the domain suffix to AD that the clients are a member of.
Please help we need to add xyz into the Domain suffix seach list
