The Blaster worm (or one of its variants, like the Welchia variant) is what caused it.
I bet this XP machine does NOT have the MS03-039 patch on it, eh?
It does need the patch.

Go there and get the XP version of the patch and install it.

One more thing. A lot of people have been confused on when their machine is hit by a Blaster worm, but then when they run an antivirus scan, it does not pick anything up.
That is because when a Blaster worm hits you, sometimes it correctly triggers the RPC vulnerability and infects the machine, and sometimes the RPC service fails, triggering the RPC alert you saw and the virus is NOT able to infect the machine.
But now, you get RPC errors, because in the process of trying to infect you, all Blaster did was mess up RPC.
