KMS SRV Records in the DNS...?

Akila

hey there , I am looking for exactly Step-By-Step directions on where and
what permissions I need to add the KMS server object (a group that contains
the Computer object) to the DNS to be able to register a SRV record in the
DNS for more then one KMS servers.

if there is one KMS server then this is not needed , but since I going to be
running more then one server I need it.
I need to know where to put the permissions (e.g on the DNS server or on the
DNS Zone or on the record itself, where) and I need to know exactly what
permissions needed.
any help would be blessed.

BTW -
1) My KMS servers would serve both 2008 and Vista SP1.
2) My KMS servers are running on 2003 x86 STD w/SP2
