RE: SQL Slammer doing the rounds again?

[Harlan Carvey <keydet89 () yahoo com>]

While I fully agree w/ Jim's advice, one thing I'm
still curious about...since we first saw Slammer...is
this - Is there a valid business reason to expose UDP
1434 to the Internet?

I've asked this before and not received any responses.

If anyone has one, I'd love to hear it.  Please
refrain from the "maybes"...I'd like to hear valid
reasons why this port is exposed.

Thanks,

Harlan
