Take a look at my page:
Look at 'Blatz' and 'Homebrew' they are my W2K DHCP servers (among other
things):

http://redhook.univ-wea.com/mrtg/

The network subnet is part of the OID, eg:
No. Address in use DHCP MIB: 1.3.6.1.4.1.311.1.3.2.1.1.2.10.6.0.0  
No. Address free DHCP MIB: 1.3.6.1.4.1.311.1.3.2.1.1.3.10.6.0.0 

10.6.0.0 is the subnet.

Anyone had beter luck ?

Wondering if anyone has any success in obtaining DHCP statistics from
Win2000 Server.
(I have provided all the info I have below - any additional will be
appreciated)
I have been through the archive with little success, only reference to ISC
type DHCP servers

I am specifically looking for the OID's which references the IN USE and
AVAILABLE addresses for the entire DHCP server (DHCP Server Statistics
window).
I have managed to obtain the rest and also able to obtain per DHCP scope.
Although with a number of scopes active on the server, I'd prefer to obtain
the summary of all the scopes as in the DHCP Server Statistics window.  The
W2K MIB (DHCP.MIB attached) refers to some table for this value ?

          noAddInUse  OBJECT-TYPE
        SYNTAX  Counter
        ACCESS  read-only
        STATUS  mandatory
          DESCRIPTION
               "This is the no. of addresses in use"
            ::= { scopeTableEntry 2 }

          noAddFree  OBJECT-TYPE
        SYNTAX  Counter
        ACCESS  read-only
        STATUS  mandatory
          DESCRIPTION
               "This is the no. of addresses that are free "
            ::= { scopeTableEntry 3 }

I have obtained addresses per scope using the OID;
1.3.6.1.4.1.311.1.3.2.1.1.2.X.X.X.X   (Where X.X.X.X is the Subnet of the
scope in question)

Other DHCP stats which I was able to obtain are;
1.3.6.1.4.1.311.1.3.1.2.0     DHCP Discovers
1.3.6.1.4.1.311.1.3.1.3.0     DHCP Requests
1.3.6.1.4.1.311.1.3.1.4.0     DHCP Releases
1.3.6.1.4.1.311.1.3.1.5.0     DHCP Offers
1.3.6.1.4.1.311.1.3.1.6.0     DHCP Acks
1.3.6.1.4.1.311.1.3.1.7.0     DHCP Nacks
