Hello all,
   More likely it's the Netlog worm, I "snort" piles of them every
day. You grabbed any of the packets and looked at the data?

From my pile o' logs:
10/12-18:48:32.736418 yyy.yy.yyy.yy:1550 ->xxx.xxx.xxx.xx:139
TCP TTL:114 TOS:0x0 ID:56344 DF
***AP*** Seq: 0xC61FAC Ack: 0x305373EE Win: 0x212B
.....SMBs.....................C......u.h.h.....................+
...ASHLEY.WORKGROUP.Windows 4.0.Windows4.0............ .\\xxxxxx\C.?????.

The y's are there to protect the guilty (I've found the majority have
shared their full C drive rw with no password, *sigh*), the x's can be
replaced by any number of my hosts, as each instance of the worm tries to
propagate to bunches of IPs.

HTH,
