Anyone know of a Windows solution similar to Netdisco?

You could also use Netdisco, which would build the DB for you.

        Interesting thought: I wonder if I could pull the spanning tree tables off my switches via SNMP and use them to 
build a database of port to MAC connections. I already have a table of all the user workstations' MAC addresses.

        ....
        Two options I see:
        
        Make a matrix of mac addresses to jack number/office numbers and then
        look at the switch's CAM table.  You'll then see what port goes to what
        office.
        
        If the switch is running spanning tree, you could sniff each port and
        look at the source MAC of the BPDU.  This should be the MAC address of
        the connected switchport.
