I haven't had much luck with this.  Microsoft doesn't expose hardly
any of this data via WMI or any other interface that I've found.
I haven't looked at Powershell yet, mostly because many of my
servers do not have it installed (2003 -vs- 2008).

The best I've been able to do is watch the event log for DHCP
server complaints about a scope getting close to consumed.  Even
*that* has been problematic, as the DHCP server service seems to
arbitrarily decide when it wants to complain.  I ended up writing
a custom plugin that watches the event log for those events, parsing
the output, and deciding on whether it's appropriate to alert.
