A Google search turned this up "Sending malformed packets to the Microsoft-ds port [TCP 445] can result in kernel resources being allocated by the Lanman service," said KPMG. "The consequences of such an attack could vary from the Windows 2000 host completely ignoring the attack, to a blue screen" Here is the link to the site http://www.vnunet.com/News/1131065 From what I read, this is a DoS attack, and from the logs you sent, I would say someone is probably trying to create a worm to exploit this, particuarly looking at the fact that you got about 100 hits. Maybe the script kiddie is trying to get his script de-bugged.
