A couple of options
1) Create a second mountpoint for the drive as a letter -- I have a
server that has "C:\mysql\data" as a separate drive. I've additionally
mounted this as "M:", and can use SNMP to look at the M: drive. I've had
issues with SNMP on windows 2000 before, it sometimes fails to report
the correct value.
2) You can also use samba, pass in a host, share, username and password,
the plugin used smbclient to do a "DIR". Seems to work for me, I knocked
up a plugin for internal use which does this, basically it does:

open(PH, "smbclient //$host/$share -U$username \"$password\" -c \"dir\"
2>/dev/null");
While (<PH>) {$lastLine = $_;}
Then checks for /NT_STATUS_BAD_NETWORK_NAME/, /NT_STATUS_ACCESS_DENIED/
and no output, then checks for the "nnn blocks of size xx. Yyy blocks"

If it finds it, it takes the number used as
100*(blockused/(blockused+blockfree))), which gives me x%

It then returns this value, and nagiosgrapher parses it to plot a graph.

(Don't ask why we have mysql on a windows server!)
