Try using IPC$. I mean, if know your Windows2k system, you should know it's an NT5. Which means you can do something like this, using nbtstat.


Displays protocol statistics and current TCP/IP connections using NBT (NetBIOS over TCP/IP).

NBTSTAT
[-a RemoteName] [-A IP address] [-c] [-n] [-r] [-R] [-s] [-S] [interval] ]

-a (adapter status) Lists the remote machine's name table given its name

-A (Adapter status) Lists the remote machine's name table given its IP address.

-c (cache) Lists the remote name cache including the IP addresses

-n (names) Lists local NetBIOS names.

-r (resolved) Lists names resolved by broadcast and via WINS

-R (Reload) Purges and reloads the remote cache name table

-S (Sessions) Lists sessions table with the destination IP addresses
-s (sessions) Lists sessions table converting destination IP
addresses to host names via the hosts file.
