I love smb threads. I thought about posting this myself, but the interessert seems rather dead
Well, this is what I did, and this works great here for finding workstations.
smbtree -NSb
Then I also added this to my .tcshrc (I'm on 10.3, but don't like Bash).
alias smb 'smbtree -NSb'
Then I only need to type 'smb' in the Terminal, and everything is revealed. Atleast I have had great success with this.
