This is a capture from last night, but now we are seeing lots of them.  One
person told me that this is the xFocus/Metaploit scan, but we have not see
it with the second part until this morning, but we had seen lots of
xFocus/Metaploit scans before ( http://www.linklogger.com/RPC_DCOM.htm ), so
I have some doubts about their analysis and perhaps this is the worm.
