fingerprinting a windows ftpd

[Franklin DeMatto <franklin () qdefense com>]

Does anyone have any advice on how to fingerprint this windows ftp server?
I can't get a banner with the server name.
HELP recieves the following response (none of the commands seemed to ID the 
server)
Does anyone recognize it?
