ip address as destination

[Vivek Malik]

hi,
i want to mount services shared by windows on my network using autofs.
i work in a setting where NetBIOS names of the compueters keep on 
changing (but their ip addresses are fixed)

I dont wanna use NetBIOS name of SMB/CIFS name of the server. I just 
have the ip address of the server.

How can set the options so that using only ip address of the server, i 
should be able to use smbclient, smbmount and pass on all the required 
options to autofs.

Please help,

cheers
