Need some details on Secure DHCP-DNS updates

Hi,

I am new to Windows DNS and DHCP with familiarity on BIND. I am looking
for some details on configuring Windows DNS and DHCP with Windows 2003
for secure updates. Found lot of documentation on configuring DHCP with
non-secure updates. But, could not find any documentation on steps to
configure Windows DNS and DHCP with secure updates.

If any of you are aware of any links on this, please reply ASAP/.

Thanks,
Lokesh
