Well.....there are a few ways to do this. Try this: From a logged in Windows box. Look at My Computer. Look at the mapped drives. Depending on the Windows OS you are using you should be able to see the share name and the server name in some fasion. In XP you may see for example
"sharename on 'Description (servername)'(F:)"

Note the sharename and servername. Now you need to ping the servername to find the IP address since your KNOPPIX box probably does not know how to resolve the servername. Enter the server name and IP address in your hosts file or use the IP address in your mount -t smbfs command for the servername.

I think that should work. Good Luck. Mike
