SMB overflow attacks

[KF <dotslash () snosoft com>]

Does anyone have log entries from a confirmed attack based on the recent 
SMB overflows?

http://online.securityfocus.com/bid/5556 and
http://online.securityfocus.com/advisories/4416

I have a client with some unusual log entries related to lanman and SMB 
headers.... the log issues are similar to the following article:

http://support.microsoft.com/default.aspx?scid=kb;[LN];Q321733

After applying the fix mentioned in the security-focus bid the server 
seemed to be happy... this makes me think the reason the server
was arrgivated is related to a DoS attack on SMB.

I just need something solid to either trace back to an attacker or a 
confirmation that I was even attacked.
