Well here is an overkill version that does the following.

1. Reads a list of systems from a file.
2. Pings it to determine if it is online or not
3. Checks if WMI is functioning correctly
4. Lists the hidden Admin shares excluding Admin$
5. Sorts the list of shares
6. Lists the free space of each hidden share
7. Does not limit to local hard drive as some SAN or other storage may not show as type 3 but the hidden Admin share still remains.

Example output
dc-svr-01 using NetBIOS is not in WINS-DNS
fs-svr-01 using NetBIOS is not in WINS-DNS
ENIGMA C$ 188407332
