Third-party DHCP hook in VC++

Hi

I'm trying to create a third-party dll to hook into the W2k DHCP server.
I've already found the explanation at msdn.microsoft.com/library/en-us/dhcp/
dhcp/dhcpservercalloutentry.asp. However, I'm looking for someone with a
working example of how to do this. I'm pretty familiar with VC++, but I
somehow guess it's not as easy as writing a simple ATL dll with
DhcpServerCalloutEntry and DhcpAddressOfferHook (example!) as exports and
then adding the dll to
HKLM\System\CurrentControlSet\Services\DHCPServer\ Parameters.

Can someone provide me with some example source code or a good
www-reference? Does anybody know if the examples work with Windows 2000
server (I find contradicting statements in the MSDN text)?

Thanks a lot
Simon
