May be an other MS Net Send Messenger spam...

Most of the time they are sent on UDP ports 1026, 1027 and 1028 from any remote port including the port 0 ...

The included data looks like this :

and other stOOpids messages...

They comes mostly from zombie PCs in the Pacific ring (check the IP addresses range..)

[220.*.*.*] , [222.*.*.*], etc.

Ref.: http://www.microsoft.com/windowsxp/using/security/learnmore/stopspam.mspx

If Windows is up-to-date this service is disabled.
And your FW block this: that's okay.

By the way: all packets from or to the port 0 must be blocked...

eMule ? Check yout rule set!
NetSendMessenger spam packets can't be interfere with UDP packets to eMule...

eMule reject these packets since they don't have the data and format required to be relayed in this p2p network...

Don't waste your time to check from where these NSM spam come from...
It comes from Zombies PC. They are remotly controlled by spammers and they used them for relaying the spam. (In pacific ring, est europa and so on...)

No Denial of Service with this.
With Windows up-to-date and theese packets blocked by the firewall nothings can happen...
