I'm not sure if anyone has run across this yet but even if they have, I think it is worth repeating:

* If you apply SP4 or any other SP to a box, you must re-install the RPC patch afterwards and then reboot even though the damn thing doesn't tell you to do so (the RPC patch that is).

What we have seen is people trying to be diligent by applying service packs and afterwards, they have shown up as vulnerable again. Yes, we reported this to MS but hae heard nothing back yet.

Anyway, just an FYI for those who are in the trenches trying to remediate this garbage.
I had also read a bunch of people coming across this on bugtraq.
