Domain Suffix Search Order. Windows Server 2003 R2 DNS,DHCP

HI,

I've got a multidomain enviroment, with two domains. The root domain of the
forest is city1.domain.net and then I have another branch in the same office:
city2.domain.net

So now I want to configure the Domain Suffix Search Order for all clients in
the network. All are windows based XP or Vista. I did some research, and
found that Microsoft implements this options in the group policies, but I've
edited the option in the default group policy for city1.domain.net, activated
it and added city2.domain.net, but still when clients get DHCP options, they
don't get the Suffix list, so I need to write the FQDN in order to point to
the computers on city 2.

Also I tried to manually create option 135 in DHCP, because my Windows
Server doesn't have it in default options. I manually created the entry, and
added it to the DCHP scope, but clients don't get the suffix list yet.

Please can anyone help me solve this?, I just need the clients to have
city2.domain.net in the suffix search order without adding it manually in
each computer, so I really dont care if it's by DHCP, or Group Policy, but
none of them is working for me..

Thanks!

Met this kind of issue, and the value is a straighforward 'unsalted'
registry entry, so you can 'push' it using a logon script, with 'regedit /s
{path}\registryfile.reg'

REGEDIT4
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"SearchList"="my.domain.net"
"UseDomainNameDevolution"=dword:00000000

Second value is optional but it stops numerous out-of-bounds connections
being attempted when the server can't be contacted.
