I don't see where you found the "confusion"...McWilliams specifically
referred to the service and even provided a link to an MS KB article.

Some of the folks on the public lists have "good firewalls"...but they
still get hit w/ this stuff. The reason is b/c some of them have to
allow DCOM/RPC portmapper (UDP 135) through for a specific purpose.

NetBIOS ports aren't used by the DirectAdvertiser application. They
are used by the "net send" command, and the NetMessageBufferSend() API
(which 'net send' uses)...however the popups most folks are seeing are
coming in over DCOM/RPC.

Again...I'm not all that clear on where you found "confusion" in the
article. To be quite honest, it was relatively clear. The only folks
who might be confused by it are those who chose not to read it
completely.
