    The easy way to do it (although not multithreaded, or fast) would be to
    use nbtdump in conjunction with a little bat/sh script looping all
    addresses. Ie: nbtdump $1, then simply cat *.html |grep "password is"
    
    Or the windows equiv of grep (or just use windows search/contains)
    Nbtdump will attempt to connect to null shares and check for user/"",
    user/user and user/password.
    
    Handy, but it often fails on matching some accounts and isn't really
    that fast.
    
    Nbtdump is on foundstone, originally made by David Litchfield
    (www.cerberus-infosec.co.uk)
    
    Hope this helps some..

    Subject: Scanning for blank admin passwords on a windows box
    
    
    
    I am looking for a fast multithreaded tool that can scan a range of IP 
    
    addresses and look for blank administrator (or other user accounts) 
    
    passwords on a windows NT/2000 server.
    
    
    
    If it can also try the username as password, server name as password
    that 
    
    would also be nice.
    
    
    
    Doing blank password scanning using the following command line syntax is
    
    
    driving me crazy!
    
    
    
    FOR /L %i IN (1,1,254) DO net use \\XX.XX.XX.%i\IPC$ "" /u:Administrator
    
    
    
    Any help appreciated.
    
    
    
    Jason
