Security Incidents: RE: Port 445 increase?

["Jim Harrison (SPG)" <jmharr () microsoft com>]

Yes; my ISA servers have logged these scans and continued on their merry way.
I have to be careful; having ISA servers between me and them can make me awfully lazy in my log scan habits...  ;-)

        Since around noon today (CST), we've really been getting hammered with tcp 445.  Interestingly, it appears to 
be a tool or worm doing the scanning.  All requests seem to follow the same basic format of ICMP, then 445, followed by 
nbname.  The requests are coming from many many different IPs, but are all directed at a single box on our network.
        
        Just curious if anyone else out there is seeing anything like this?
        
        Thanks!
