And those sites during slammer that blocked 1434, as was advised when the
patch was made available, though it was advised even long before that,
were largely unafected.  Sites that are properly blocking 135 and it's
protocolcs will most likely be unaffected from any new worm wishing to
exploit this repeat problem with DCOM/RPC.

OK, so you're a Ph.D.  Just don't touch anything.
