I know the topic has praticly been beaten to death allready but I felt that this knowledge should be shared ASAP.
The Computer Emergency Response Team (http://www.cert.org) has released an advisory regarding the RPC/DCOM worm spreading.
The advisory can be found at the following URL:
http://www.cert.org/advisories/CA-2003-20.html

The document contains valuable information regarding the worm and ways to help further spreading applying patches and reckonising infected boxes.

I searched the other post and did not find this information and I thougt if I posted it as the xxth reply it would not get the attention it deserves.

Sincerely
Cerveza

Oh yeah, I forgot to add.
