What is the code for SMB scan with no password?

I remember reading there was some way in the service mode to enable that, but now I can't find it.
TIA

I think you can go to : User Tools - System Settings - Interface Settings - Default Username & password. Just check there somewhere and type in a default username and password for SMB. Usually using username:Administrator and blank password works with WinXP
