Deanna, are you trying to map a sharename of a server from your windows machine? If so you can simply connect to the share through windows:
Start>run then type \\Server_IP\Sharename
or by server dns name if you know it.
Start>run then type \\ServerDNS_mame\Sharename
or you can do it from command line:
e.g
c:\net use * \\server_ip\sharename
