Blaster Recurrence

["E. Jimmy Allotey" <jimmy () allotey com>]

I am seeing some new occurences on reformatted machines on my network.
They appeared on machines which were reformatted and connected to the
network before installation of patches and anti-virus software
(idiots!!!!) We have checked all the other machines here which were
unaffected and they are fine.  

Our perimeters are blocked on all the named ports and yet the beast
managed to get in....

For fear of sounding stupid, does anybody have any ideas??
