[Dshield] UDP 137 Scans

Greetings:

We are getting whacked pretty good by 137/UDP scans -- a different block of 3 to 7 IPs in rapid succession every few minutes. Presently, these scans are outnumbering 135/TCP scans by a factor of 2 or 3 to 1.

These are being blocked on our DSL router and I have no easy way of doing a packet capture or submitting logs.

This all started about noon EDT.

Any idea what is going on here?
