    We had one machine infected by the original Code Red in July.  It was 
    patched and rebooted and was fine (despite being exposed to lots of 
    probes) until CR II arrived when it was again compromised.  This was a 
    mild disaster since CR II then spread on our internal network behind 
    the firewall. 
    
    [ yes we had scanned and shutdown/patched *most* of the vulnerable 
    systems regardless of whether they were protected by the firewall or 
    not -- with 1000s of machines that come and go you never get them all 
    :( ]
    
    I too would be very interested to know how this happened and if there 
    are any extra precautions one can take.
